Exercise Progression in Rehabilitation: From Rest to Return to Sport

What is Exercise Progression in Rehabilitation?

A progressive rehabilitation exercise program adjusts the difficulty of the exercises to your abilities and goals. Your physical therapist can modify the resistance, the number of repetitions, the frequency, or the movements. They take into account your symptoms and the activities you want to resume.

The Scientific Foundations

The physical stress theory, proposed by Mueller and Maluf, describes how tissues respond to the stresses they are subjected to¹. In this model, the response depends, in particular, on the intensity and duration of the stress.

In practice, your physical therapist tailors the exercises based on your evaluation and your progress. A general theory alone is not enough to determine the appropriate intensity for you.

Objectives of Progression

A rehabilitation program is designed to prepare you to resume your activities. The exercises focus on the skills you need for your job, hobbies, or sports. The program can be used to:

• Adjust the difficulty based on the observed response
• Gradually developing strength, endurance, and flexibility
• Practice the movements relevant to the targeted activities
• Preparing for a return to sports or professional activities
• Fostering Trust and Participation in Activities

Difference from the Traditional Approach

A personalized program specifies which exercises to do, how to perform them, and when to adjust them. It differs from a set list of exercises because your physical therapist reviews the choices with you. Your challenges, your goals, and your response to the program guide these changes.

How Does Exercise Progression Work?

Exercise progression involves adjusting the intensity, movements, and tasks based on your assessment. Your physical therapist takes into account the necessary precautions, your mobility, strength, coordination, and the demands of your daily activities.

Five variables to adjust

Protection and Constraints

Medical guidelines specify the movements and levels of exertion permitted after certain injuries or surgeries. Your physical therapist takes these into account when selecting exercises and adjusting their difficulty.

Mobility

Mobility exercises focus on movements that are useful for your activities. You can perform a movement on your own or with assistance, depending on your condition. The range of motion and frequency can be adjusted to suit your needs.

Strength and Endurance

Strength and endurance exercises build the ability to exert or sustain effort. Progressive overload involves gradually increasing the demand, for example, by adding resistance or repetitions. These adjustments are tailored to your abilities and the guidelines specific to your condition.

Duties and Coordination

Coordination exercises help you practice useful movements, such as getting up, climbing a step, or throwing an object. Balance exercises are useful for tasks that require you to control your position.

Activity Requirements

Your physical therapist assesses the demands of the activity in question. Carrying a box, running, and returning to a contact sport all require different abilities. The program tailors the permitted levels of exertion to the specific activity you’re performing.

These aspects are interrelated: climbing a step requires mobility, strength, and balance. Their importance varies depending on your physical condition. Post-surgical restrictions may require you to take specific steps.

Variables Adjusted During Progression

Your physical therapist can modify several aspects of an exercise. The table lists options to choose from depending on the goal; these are not mandatory steps:

Adding repetitions increases the total workload. Changing the speed or position can also alter the amount of effort required. Your physical therapist takes these effects into account when adjusting your program.

Adjustment Marks

Your physical therapist combines your observations with measurements to determine the appropriate adjustments. For lower back pain, the progress indicators considered include, among other things, perceived exertion, pain, and measured functional abilities:

• Pain Response: You describe your symptoms during and after exercise, as well as how they affect your daily activities.
• Range of motion: Your physical therapist measures the movements required for the target task.
• Strength: Your physical therapist assesses your ability to perform the required exertion.
• Functional tests: Selected tasks, such as a jump or a change of direction, help assess a person’s return to sports².
• Quality of movement: Your physical therapist observes how you perform the task and any difficulties you encounter.

A single test result does not fully reflect your ability to resume an activity. Your physical therapist takes into account a combination of test results, your symptoms, medical recommendations, and your goals.

Adaptation Mechanisms

Exercise can alter muscular, nervous, and cardiovascular function. These adaptations depend on the exercises performed and the condition being treated¹:

• Muscles: Strength training aims to increase strength or the ability to repeat an effort.
• Tendon or ligament: The response to stress varies depending on the tissue and the injury; protective measures remain important.
• Cardiovascular system: Endurance activities place demands on the heart and circulatory system to support physical exertion.
• Movement control: Practice helps develop coordination for a specific task.

Progress is made over the course of each session. Your physical therapist also adjusts recovery periods based on the level of exertion required, your other activities, and how you respond.

Which conditions benefit from exercise progression?

A progressive exercise program is part of the treatment for many injuries and conditions, including sprains, tendinopathies, knee osteoarthritis, and chronic lower back pain. The expected benefits and precautions vary depending on the condition. The program focuses on the activities that cause you problems.

Sprains and Ligament Injuries

After a lumbar sprain, this program can help you gradually resume the movements and activities that have been limited by pain. The physical therapist will select the exercises based on your evaluation.

Ankle sprains, knee sprains—including injuries to the anterior cruciate ligament—and neck sprains each require different precautions. The severity of the injury and the possibility of surgery influence the level of activity permitted.

Tendinopathies and Tendinitis

Exercise programs for tendinopathy adjust the load placed on the tendon. Shoulder tendinopathy and patellar tendinopathy affect different tendons. They may therefore require different exercises³.

The effects of the exercises vary depending on the tendon, the program, and the individual³. Your physical therapist monitors your pain, the activities you can do, and your tolerance for exertion to adjust your treatment.

Knee pain

Exercises can be part of the treatment for patellofemoral syndrome, meniscal tears,knee osteoarthritis, or instability following a sprain. The program addresses the difficulties identified during the evaluation, such as climbing stairs or standing up from a chair.

Physical therapy for knee pain tailors treatment to your diagnosis and your activities. Understandingthe anatomy of the knee can also help you discuss your condition.

To learn more about the causes, symptoms, and treatments for knee problems, consult our complete guide to knee pain.

Shoulder pain

Exercises for shoulder pain should be tailored to the movements that are difficult for you and how your symptoms respond. A rotator cuff tear, capsulitis (also known as frozen shoulder), and shoulder instability each require different approaches.

Our comprehensive guide to shoulder pain covers common symptoms, possible causes, and treatment options.

Lower back pain

For persistent lower back pain with no specific identified cause, exercise likely reduces pain compared with no treatment or usual care. The average improvement in activity limitations is smaller⁴.

Your program may include mobility exercises, strength training, or practice with daily activities. Your physical therapist will tailor these exercises to your response. Our comprehensive guide to back pain also covers other lower back conditions.

Sports injuries

Sports physical therapy prepares you to return to the activities specific to your sport. The evaluation takes into account the injury, the athlete’s abilities, and the risks associated with the activity. Here are some examples of situations:

• Running Injuries (Tibial Periostitis, Iliotibial Band Syndrome)
• Pivot sport injuries (knee sprains, instabilities)
• Throwing injuries (pitcher's shoulder, pitcher's elbow)
• Injuries from contact sports (concussions, whiplash)

After a concussion, resuming activities and sports requires following specific guidelines. Returning to activities that involve a risk of falling or physical contact requires medical clearance. Strength-training exercises are not a substitute for this process.

Chronic conditions

For knee osteoarthritis, exercise can improve pain and daily activities in the short term⁵. A Cochrane review updated in 2024 notes that the extent of the benefits remains uncertain and does not always represent a noticeable change for the individual. For persistent pain from another cause, the choice of exercises depends on the diagnosis and your goals.

What happens during an exercise progression program?

During an exercise progression program, your physical therapist assesses your abilities, helps you choose exercises, and monitors your progress.The initial assessment helps determine your goals and the exercises you should do at home.

Comprehensive Initial Assessment

The first appointment is designed to help us understand your condition and the activities you’d like to resume. The physical therapist will ask you questions and determine which tests are necessary:

Detailed Medical History: Describe your symptoms, when the problem began, your activities, and your goals. Objective Assessments: The physical therapist measures range of motion, assesses strength, and observes relevant activities. He or she may also examine tender areas. Identifying Limits: The physical therapist identifies areas where the patient has difficulty with strength, mobility, coordination, or endurance. Setting Goals: Together, you set specific goals, such as walking for longer periods or resuming a work-related task.

These observations will help you choose the initial exercises and the metrics that will be used to track your progress.

Personalized Program Planning

After the evaluation, the physical therapist will work with you to develop a program. This program will specify:

Exercise Selection: The physical therapist selects exercises that are helpful for your goals and that you can perform given your current abilities. Initial Dosage: The program specifies the planned resistance, sets, repetitions, and frequency. Progression criteria: You agree on the observations and measures that will guide a change in difficulty. Long-term plan: You discuss which activities to resume and when to reassess the program.

Supervision and Instruction

The physical therapist will show you how to perform each therapeutic exercise. He or she will check to make sure you understand and adjust the instructions as needed. He or she may:

• demonstrate each exercise
• monitor your initial implementation
• correct your technique in real time
• help you describe your symptoms and how they affect your daily activities
• teach you how to monitor your own response to the exercises

You can practice the exercises during the session and ask any questions you have before doing them again at home.

Home program

Part of the program can be completed between appointments through at-home exercises. The physical therapist will provide you with:

Written or Video InstructionsClear documentation for each exercise, including specific parameters (sets, repetitions, frequency). Independent Progression: Instructions for modifying certain exercises and situations in which to request a reevaluation. Tracking Tools: A journal is a good way to keep track of the exercises you've done, any difficulties you've encountered, and how your symptoms have responded.

The at-home program takes your schedule and the equipment you have available into account. Let us know which exercises are difficult to fit into your day so we can discuss other options.

Regular Reassessments

Periodic reassessments make it possible to:

• Monitor strength, range of motion, and function
• Adjust the program based on your response to exercises
• Check whether the exercises still align with your priority activities
• Reevaluate the diagnosis, goals, exercises, and dosage if the expected changes are not observed
• Discuss the progress made and the remaining challenges

The physical therapist will repeat the relevant measurements under conditions that are as similar as possible. He or she may add other tests if your needs change.

Continuous Adjustments

Progress doesn't always follow a straight line. Your program may change depending on your progress or your circumstances:

Observed response: An exercise that is well tolerated and has become easy can be adjusted if a higher intensity helps you achieve your goal. Worsening of symptoms: You work with the physical therapist to assess their intensity, duration, and impact on your daily activities before deciding on a change. Different Evolution of the Objective: The physical therapist will review the assessment and exercises if the difficulties persist. Life Events: Your schedule, your level of fatigue, or access to equipment may require some adjustments.

The goal is to maintain a program that is both useful and achievable. A temporary adjustment doesn't necessarily mean you've lost your progress.

Two-way Communication

You can contribute to decision-making by sharing the changes you've observed, your questions, and the constraints that affect the program:

• Report any changes in your symptoms
• Report exercises that seem too easy or too difficult
• Discuss the obstacles that are preventing you from following the program
• Ask questions about why these exercises were prescribed
• Share your concerns or frustrations regarding the pace of progress

Your observations help the physical therapist understand what is happening between sessions. You can then decide together on any necessary adjustments.

What are the most common questions about progressing through rehabilitation exercises?

The most common questions about exercise progression relate to the duration of the program, pain, the frequency of sessions, and returning to normal activities. The answers below will help you discuss your own program with your physical therapist.

How long does an exercise progression program last?

The duration of the program depends on your physical condition, the precautions you need to take, and the activities you want to resume. Regular reassessments allow us to adjust your goals as you make progress.

Ask what changes you can make between appointments. Walking longer, lifting a weight, or resuming a task can show progress even if some symptoms persist.

How quickly can I progress with my exercises?

Your pace of progress depends on your fitness level and how you respond to the exercises. The common rule of a 10% increase per week is not a safety threshold that applies to all runners⁶. Therefore, it cannot be used to automatically determine the pace of a rehabilitation program.

You can discuss making a change once the exercise becomes easier and your target activities are progressing well. After surgery, medical restrictions still apply even if you feel ready.

An adjustment can involve resistance, repetitions, or duration. Your physical therapist will tell you which changes you can make on your own and in which situations you should seek their advice.

Is it normal to feel pain during rehabilitation exercises?

You may experience some discomfort during rehabilitation exercises. This does not automatically mean you should stop or increase the difficulty. The decision depends on your condition, how your symptoms typically respond, and the instructions you have received.

Response to watch for: Note the intensity and duration of the discomfort, how it changes after the session, and its effects on your activities. Signs to Have Evaluated: Stop exercising and seek medical advice immediately if new pain is accompanied by significant swelling, redness, or a marked loss of function. A warm, painful joint accompanied by a fever requires urgent medical evaluation.

A scale from 0 to 10 helps describe the pain, but the number alone does not determine the course of action. Also mention what you can do and what has changed since the last session.

Pain may occur with or without visible injury⁷. In tendinopathy, for example, the physical therapist considers the symptoms and activity limitations to adjust the load³. New or unusual pain warrants special attention.

How do I know if I'm progressing too quickly?

Pain that continues to worsen over time or activities that have become more difficult may indicate that the program needs to be adjusted. Here are some changes to look out for:

• Increasing pain: Your symptoms are getting worse compared to their usual level.
• Morning symptoms: Unusual pain or stiffness occurs upon waking.
• Increased sensitivity: Activities that were previously tolerated now trigger your symptoms.
• Difficult recovery: Fatigue or symptoms remain more severe than usual between exercise sessions.
• Loss of function: Certain movements or activities become more difficult despite the exercise program.
• General fatigue: Exhaustion or disrupted sleep limits your ability to participate.

These changes alone do not prove that you have progressed too quickly. Their intensity, duration, and context help you decide whether to continue with the program, modify it, or request a new evaluation.

What should I do if my exercises become too easy?

If an exercise becomes too easy, it can be continued, modified, or replaced depending on the goal, function, and response. Several options can be discussed:

Contact Your Physiotherapist: Discuss the proposed changes and the indicators that would warrant a reassessment before modifying the program. Autonomous increase, as instructed: If your physical therapist has explained how to progress, you can change one variable at a time—for example, add a repetition or slightly increase the resistance. Reassess the difficulty: An easy exercise can still be useful for practicing a movement or maintaining a skill. It doesn't always have to get harder.

Changing just one variable at a time helps you track your response. Make a note of the change and what you observe during the following sessions.

How many times a week should I do my exercises?

The frequency depends on the exercises, your fitness level, your goals, other activities, and how your body responds:

Mobility: Your physical therapist will determine the frequency based on the movements you need to work on and your tolerance for them. Strength and Endurance: The intensity of your workout and your recovery time affect the interval between sessions. Chores or Sports: The program takes into account the activities you already have in your daily routine and workouts.

The program should specify a clear frequency for each exercise. If it is difficult to stick to this frequency, discuss a realistic schedule with your physical therapist.

Can I play sports during my rehabilitation?

In some cases, you may be able to continue participating in an appropriate physical activity during rehabilitation. Your physical therapist will assess the risks associated with your injury and any necessary adjustments before giving you advice:

Protection or Mobility: Follow any restrictions related to your injury or surgery, even if an activity causes only mild pain. Strength or Endurance: Another activity can help maintain certain abilities as long as it adheres to the restrictions. Depending on the injury, cycling or deep-water running may be an option for a runner. Job-Specific Tasks: The return to training can begin with modified exercises and then progress to the sport's usual demands. Decision to Return to Sports: Full participation is determined based on criteria specific to the sport, the injury, and the athlete.

A return-to-sport plan may include clinical and functional measures selected based on the injury, the sport, and the desired outcome; no single measure alone determines each decision.

What reference points are used to adjust a variable?

A variable can be adjusted after considering relevant benchmarks for the condition, the targeted activity, and the response:

Possible reference points:

• Your response to the sessions, including the duration of your symptoms and their impact on your activities
• The movements required to perform the targeted activity
• How you complete the tasks to be reviewed
• Test results relevant to your condition

Guidelines for Returning to Sports:

• Your ability to perform quick movements or changes in direction in sports
• Your Response to Resuming Training
• Your confidence in resuming sports activities

Following anterior cruciate ligament reconstruction, one study found fewer new injuries among individuals who passed the tests for returning to sports. However, the difference was too small to confidently conclude that these criteria had a protective effect⁸.

In this study, a delayed return to sports involving pivoting—up to nine months after surgery—was associated with fewer new injuries⁸. This finding does not mean that waiting nine months is sufficient: strength, athletic ability, and the healthcare team’s recommendations must still be taken into account.

Your physical therapist will take your test results into account along with your progress, your goals, and your confidence. The healthcare team will then discuss the conditions for resuming your activities with you.

Should I continue exercises after physiotherapy ends?

Some exercises may still be helpful after you finish physical therapy to maintain your abilities or continue working toward your goals. The choice depends on your condition and your activities:

Condition-Based Prevention: Your physical therapist will let you know if a specific program can reduce the risk of recurrence in your case. Maintaining Capacity: You choose activities that build strength, flexibility, or endurance—skills that are useful in everyday life. Pursuit of Objectives: The exercises can be adapted to your usual activities or a new goal.

Before your follow-up appointment ends, ask which exercises to continue, how often to do them, and when to schedule your next appointment. The plan may change based on your needs.

How can I objectively measure my progress?

Your physical therapist measures your progress using tests and exercises related to your goals. There are several possible methods:

Strength tests: Manual muscle testing classifies strength based on the ability to move against gravity or resistance. A dynamometer is a device that measures force, for example, in newtons. Comparing both sides can be helpful, but the opposite side is not always a normal reference point. Amplitude Measurements: A goniometer, an instrument used to measure angles, is used to record the degrees of movement in a joint. Functional Tests: A test of jumping, balance, speed, or walking measures a skill relevant to the targeted activity. Job Descriptions: Describe the difficulties you experience in your daily activities. The questionnaire you choose depends on your condition. Exercise Journal: Record the exercises performed, the number of repetitions, the weights used, and any reactions observed.

These measures allow you to track your progress, even if it varies from session to session. They complement your description of what is becoming easier or remains difficult.

What should I do if I miss several days of exercises?

After several days without exercise, resume your routine according to the guidelines provided by your physical therapist. If you haven’t received any guidelines for resuming exercise, ask what intensity level to use.

Avoid cramming all your missed sessions into a single day. The goal is to find a routine that suits your current abilities.

An illness, a new injury, or unusual symptoms can change your plan. Be sure to report these issues before resuming strenuous activity.

How to prevent setbacks during your progress?

A tailored program and monitoring of changes can help manage your recovery, but no strategy can prevent all relapses. Here are some guidelines to discuss with your physical therapist:

Use relevant criteria: Track the skills and activities that matter most to your goal. Interpret the symptoms: A slight increase in pain or stiffness does not automatically require a change to your exercise program. Consider its duration, intensity, and impact on your daily activities, and then follow the agreed-upon guidelines. An unusual or significant symptom warrants consulting a healthcare professional. Balance all the forces: Take into account exercise, work, and sports all in the same week. Discuss any significant increases before adding them. Consider recovery: Report any fatigue, lack of sleep, or other factors that limit your ability to follow the program. Watch the movement: Work with your physical therapist to find a way to perform the movements that suits your abilities and your goals. Communication: Report any significant changes, then work with your physical therapist to determine whether they require an adjustment or an earlier evaluation.

For Achilles tendinopathy or any other sports injury, returning to sports requires a shared decision. The athlete, physical therapist, and, if necessary, the coach discuss the athlete’s abilities, the demands of the sport, and the acceptable level of risk².

Is exercise progression effective for chronic pain?

A progressive exercise program can help some people living with chronic pain resume their activities. The results depend on the condition and the program. Several factors guide the support provided:

Starting Point: Choose exercises that you can do based on your current abilities. Interpretation of Symptoms: You agree on the reactions to monitor and the changes that require consultation. Functional Objectives: You focus on activities that are important to you, such as walking, gardening, or working. Understanding Pain: The physical therapist helps you interpret these fluctuations and identify situations that require a reassessment. Complementary Options: Depending on your situation, the plan may also include information, manual techniques or support for stress-related issues.

The program tracks both your symptoms and your participation in activities. Persistent pain does not mean you have to wait for it to go away before engaging in any activities.
