Exercise Progression and Regression in Physical Therapy

Exercise progression in physical therapy comes down to a working rule: move up a step when the patient can do the current version with good control, at the effort you set, and without a flare the next day. Regress when pain climbs past the agreed limit, the next morning is worse or fatigue breaks down the technique. Either way, many physios change one lever at a time (load, reps and sets, range, speed, base of support, lever length, complexity or frequency) and write the rule into the home exercise program (HEP), so the patient can move a step up or down between visits. New symptoms are different: they mean stopping that exercise and checking what has changed.

The first half of this guide is the reasoning. The second half is practical: four ladders built from exercises in our library, and a five-line template for putting the rule in a HEP.

Why exercise progression matters in physical therapy

A dose that was hard in the first week can feel easy a few weeks later, and a dose that stays easy gives the body little reason to keep adapting. The 2009 American College of Sports Medicine (ACSM) position stand on progression opens on that point: to keep adapting toward specific training goals, a resistance program has to progress. Kraemer and Ratamess describe progression as changing the program variables over time to maintain or advance specific goals and to avoid overtraining. Both halves of that sentence apply in rehab. Too little and the patient plateaus; too much too soon and the symptoms flare.

The second principle is specificity. People get better at what they practice, so every ladder needs a destination. A patient who wants to manage the stairs at home needs a ladder that heads toward loading one leg on a step, not more reps of a seated exercise. The 2011 ACSM stand by Garber and colleagues says the program should be modified according to the person's habitual activity, physical function, health status, exercise responses and stated goals.

One catch: ACSM wrote both stands for apparently healthy adults. With a patient, the problem sets the ceiling: how easily it flares, how far the tissue has healed, and any surgical protocol. Garber and colleagues also note that gradual progression of intensity and volume may reduce the risks of exercise. That is the argument for small steps.

The levers you can change to progress or regress an exercise

These are the eight levers this guide uses. Regression is the same lever moved the other way.

Lever	To progress	To regress	Example from a home program
Load	More weight, a firmer band, more body weight on the working side	Less weight, a lighter band, hands helping	Calf raises on two feet, then on one
Reps and sets	More reps, then an extra set	Fewer reps, or one set	2 sets of 8 up to 3 sets of 12
Range	Deeper or bigger movement	Smaller movement, stopping short of the painful part	Mini squat, then a deeper squat
Speed	A slower lowering, or a pause at the hardest point	A steady, normal pace with no pause	Lowering onto the chair over 3 s
Base of support and stability	Narrower stance, one leg, a softer surface, less hand support	Wider stance, both feet, a hand on the counter	Semi-tandem, then tandem, then one leg
Lever length	Body closer to horizontal, or a longer lever	More upright, or a shorter lever	Wall push-up, then floor push-up
Complexity	Eyes closed, head turns, a reach or a second task	Take the extra task away	One-leg balance, then with eyes closed
Frequency	More sessions a week	Fewer sessions, more rest days	2 strength sessions a week, then 3

A few of these need a note.

Load is the lever the ACSM 2009 stand is most exact about. Once the current weight allows 1 or 2 reps above the target number, it suggests a 2 to 10% increase. Home equipment rarely comes in steps that small. Going from a 1 kg (2.2 lb) to a 2 kg (4.4 lb) dumbbell doubles the load. So at home the next step is usually another lever: a lower seat, a slower lowering, one leg instead of two, or the next band color up.

Speed works in both directions. The ACSM 2009 stand recommends a moderate speed (1 to 2 s up, 1 to 2 s down) for intermediate and advanced strength training, and fast movements with light loads for power. In rehab, slowing the lowering phase or adding a pause is a common early progression. Speed and power usually come later, for patients who need them for sport or for catching themselves from a trip. That order is common practice; no trial has tested it.

Frequency is easy to overlook. The same ACSM stand suggests 2 to 3 strength sessions a week for beginners and 3 to 4 for people with about 6 months of training. Early range-of-motion work is usually set more often than that. Again, this is common practice, and no one has tested the dose.

Many physios change one lever at a time and leave the rest alone. Then, if symptoms flare, you know which change did it and which step to undo. It is common practice rather than trial evidence, but it makes the next decision much easier.

How do you know when to progress an exercise?

In practice, progress when four things line up: the symptoms settle, the effort has dropped, the movement looks right, and the next step moves the patient toward their goal. If one of them says no, keep the current step or change a different lever.

Pain during the exercise and the next morning

Silbernagel and colleagues tested a pain-monitoring model in people with Achilles tendinopathy. During exercise, pain up to 5 out of 10 was accepted. Afterwards it could also reach 5, as long as it had settled by the next morning and pain and stiffness did not build from one week to the next. Patients who carried on running and jumping under these rules did as well as the group that rested from them, and no negative effects were found.

Only Achilles tendinopathy was studied. Physios commonly carry the idea over to other long-standing muscle, joint and tendon pain, though that has not been tested, and a more irritable problem often gets a lower ceiling. The 3 out of 10 limit in the knee example in the FITT principle guide is one of those cautious choices, not a figure from research. After surgery or a recent injury, the surgeon's plan or the local protocol takes priority.

A useful question at every review is "how was it the next morning?" If the answer is "worse", the last step was probably too big, whatever the patient felt during the set.

Effort: RPE and reps in reserve

Rating of perceived exertion (RPE) asks how hard the effort felt on a number scale. In a JOSPT study by Bove and colleagues, adults rated knee extension exercise from 0 to 10. Their ratings were highly repeatable from test to retest, but they matched percentage of one-repetition maximum poorly, most of all at the intensities people usually train at. So RPE is good for spotting that the same exercise now feels easier. It will not tell you the percentage of maximum.

Reps in reserve (RIR) asks how many more good reps the patient could have done at the end of the set. Zourdos and colleagues built an RPE scale around it and found it a practical tool for adjusting training load day to day, although their subjects were 29 young lifters doing squats, not rehab patients. RIR pairs well with the ACSM rule: if the patient finishes the target reps with 1 or 2 more good reps left than you planned, on two sessions running, the exercise is ready to change. The study did not test that trigger in patients; it is simply a practical way to use the scale.

Quality of movement

Watch the exercise before you change it. Technique drifts at home, and a patient who has added reps by letting the knee fall inward or the hips sag has not really progressed. Many physios look hardest at the last few reps of a set, where fatigue usually shows. If the form holds to the end, the patient is ready. If it breaks down, keep the step or shorten the set.

The patient's goal

Specificity decides which lever to pull. A retired teacher who wants to get off a low sofa needs a sit-to-stand ladder that ends on a lower seat. A netball player returning to court needs single-leg loading, then speed and landing. Ask what the patient wants to get back to, and check that each step moves toward it. When one lever runs out, for example the bench is as low as it goes, switch to another rather than piling on reps.

When to regress an exercise

Stepping back is a normal part of any plan. The usual reasons:

A flare: pain climbs past the agreed limit during the set, is clearly worse the next morning, or pain and stiffness build from one week to the next.
Fatigue: the form breaks down early, the reps drop sharply, or the patient is run down by poor sleep, illness or a hard week.
A setback elsewhere, such as a new injury, an illness, a hospital stay or a long break from the program.
New symptoms: numbness, tingling, weakness, swelling, the joint giving way, or pain in a new place.

A flare or fatigue usually means one step back on one lever. Hold there until the symptoms settle and the effort drops again, then climb back up. If the symptoms have not settled after a few days on the lower step, stop that exercise and check with the physio. Fatigue from a bad day may only need a lighter session, not a change in the plan. A setback elsewhere may need a bigger step back, and after an illness or a hospital stay the program should be checked before the patient restarts it.

The fourth is different. New symptoms mean stopping that exercise and checking what has changed, not just dropping a level. Some of them are red flags, listed at the end of this guide.

Tell the patient in advance that dropping back a step is allowed, and write down which step, so a bad day does not turn into a week off. The adherence guide covers the wider reasons patients stop.

Worked progression ladders

The ladders below use real exercises from our library. Each rung changes mainly one lever. Not every patient starts at the bottom, and not every patient needs the top. The numbers on each exercise page are general starting ranges, and your physio will adjust them.

Pushing: wall push-ups to full push-ups

Rung	Exercise	Main lever
1	Wall push-ups	Most upright; step the feet back to make it harder
2	Incline push-ups	Hands on a sturdy bench or counter; lower the surface over time
3	Knee push-ups	On the floor, with a shorter lever
4	Push-ups	Full lever on hands and toes
5	Decline push-ups	Feet raised, for people who need more load

Ebben and colleagues measured the force through the hands in 23 recreationally fit adults. Push-ups with the hands raised on a box and push-ups from the knees both produced lower forces than the regular push-up, and raising the feet produced higher forces than any other version. The study did not test wall push-ups, and its abstract does not rank the knee version against the raised-hands versions. So treat the order of rungs 2 and 3 as flexible and let the patient's form decide.

One way to write the rule: "When 3 sets of 12 keep a straight body line to the last rep, two sessions running, move to the next rung and start again at the low end of that page's range, for example 2 sets of 8." The numbers are an illustration that fits the ranges on these pages, not a tested threshold. After shoulder surgery, a shoulder fracture or a dislocation, or a broken wrist or elbow, putting weight through the arms usually comes later, so the surgeon's or physio's plan sets when rung 1 can start.

Calf: two feet, then one, then extra load

Rung	Exercise	Main lever
Step back	Isometric calf raise hold	No movement, on one leg or both, for when rising and lowering irritates a sore tendon
1	Calf raises	Both feet on the floor
2	Eccentric calf raise	Up on two feet, down on one
3	Single leg heel raise	Up and down on one foot
4	Single leg heel raise with added weight, such as a backpack	More load on one leg

Going from two feet to one puts all of the body weight through one calf instead of sharing it between two, which is a big jump. Rung 2 splits it: the patient rises on both feet and only lowers on the working leg, the halfway step the single leg heel raise page also describes. Putting it before the full single leg version is common practice; nobody has tested the order. Adding weight such as a backpack later is the next step the eccentric calf raise page describes.

Two other pages sit beside this ladder rather than above it. The calf raise on a step and the weighted calf raise are both done on two feet, so they suit a patient who needs more range or load before one leg is manageable. The step version adds range only once the physio lets the heels sink below the step. Check where the tendon pain sits first. If it is where the Achilles joins the heel bone, physios usually keep the heel at step level or on the floor, as the calf raise on a step page explains.

For tendon pain, the next-morning check does most of the work. If the Achilles or calf is clearly more painful or stiff the next morning, drop back a rung. After an Achilles tendon repair or ankle surgery, each rung comes in at the stage the surgeon's protocol allows. For patients who want to know how this fits a whole program, the Achilles tendinopathy page shows the stages.

Getting up: from the armrests to a squat

Rung	Exercise	Main lever
1	Sit to stand using armrests	Hands help on the way up and down
2	Sit to stand from a high surface	No hands, seat raised
3	Sit to stand	Standard chair, arms held out; lower the seat bit by bit
4	Sit to stand with staggered feet	Weaker foot back, so that leg takes more of the work
5	Squat, then goblet squat	No chair, then added weight

The levers in this ladder have been measured. In a review by Janssen and colleagues, chair seat height, use of the armrests and foot position had a major influence on the ability to stand up. A higher seat lowered the moments needed at the knee by up to 60% and at the hip by up to 50%, and using the armrests lowered the moments needed at the hip by 50%. So lowering the seat and taking the hands away are real increases in load, not small tweaks. Janssen and colleagues note that more study is needed on how these factors interact, so the order of rungs 1 and 2 can be swapped to suit the patient.

A progression line might read: "When you can stand up 10 times without your hands and without rocking, two sessions running, take one cushion off the seat." The knee osteoarthritis program shows staged progression in use, from mini squats and squats to step-ups and split squats. If you have had a hip or knee replacement, get the go-ahead from your surgeon or physio before you try a squat. Some operations limit this kind of work for the first months, so the timing depends on your surgery.

Balance: narrowing the base of support

Rung	Exercise	Main lever
1	Semi-tandem stance	One foot half a length ahead; harder than feet together
2	Tandem stance	Heel to toe, long and narrow base
3	Single leg stance	One foot
4	Single leg balance with eyes closed or single leg balance on a cushion	Vision taken away, or a moving surface

Within each rung there is a second lever: hand support. Two hands on the counter, then one, then fingertips, then hands hovering just above it. The Sherrington review of 88 trials found that exercise reduced the rate of falls in community-dwelling older people by 21%, with larger effects from programs that challenged balance and involved more than 3 hours of exercise a week. That is one reason many physios treat a rung that feels easy and steady as a sign to move on, though the review did not test when to progress.

Do every rung next to a kitchen counter or a solid chair. Wear flat shoes that fit well and grip the floor, not socks, tights or bare feet. If the patient has fallen in the past year or feels unsteady, a hand stays on the support and the physio decides when it comes off.

A sudden loss of balance is different. Call emergency services straight away for any sign of a stroke, even if it goes away: sudden dizziness with unsteadiness or falling over, a face that droops on one side, an arm you cannot lift or keep up, slurred or muddled speech, weakness or numbness on one side of your body or face, sudden blurred vision, double vision or loss of sight, or a sudden severe headache.

How to write progressions into a home exercise program

If the progression rule lives only in your head, the patient has to wait for the next appointment to move on. So write five lines for each exercise.

Line	Example for a calf program
Today	Calf raises on both feet, 3 sets of 12, every other day
Move up when	3 sets of 15 are easy on 2 sessions in a row, and the Achilles is no worse the next morning
Next step	Up on two, down on one (eccentric calf raise), 2 sets of 10
Step back if	The Achilles is clearly more painful or stiff the next morning: go back to 2 sets of 10 on both feet for a few days
Stop and call if	Any of the warning signs below

Copy the same numbers into the plan section of your note, so whoever sees the patient next can carry on from there. The SOAP notes guide covers that section, and the home exercise program guide covers choosing the exercises and setting the first dose.

At the review, work through the same order every time:

Watch every exercise before changing anything.
Ask how it felt during the set and the next morning.
Ask how many sessions they actually did, and make it easy to admit to fewer.
Count something you can compare next time, such as single leg heel raises on each side or stands without the hands.
Make one call per exercise (progress, keep, regress or drop) and change no more than one lever.

PocketPhysio lets you set the dose for each exercise (sets, reps, hold time) and add a cue of your own. That cue is where the "move up when" and "step back if" lines go. At the next visit, the last program you sent is there to build on. It reaches patients as a link, by SMS or email, through the Pocket Physio Care app, or on WhatsApp, and every exercise comes with a video and a voice guide.

When to stop, whatever the plan says

The progression rule is for ordinary exercise discomfort. The symptoms below come first, whatever rung the patient is on, and every patient should know to stop and get help for them:

Chest pain or pressure, dizziness or feeling faint, a racing or irregular heartbeat, or being far more out of breath than the effort should cause.
Your calf or thigh becomes swollen, warm, tender, red or darker than usual, or has a throbbing or cramping pain that feels different from normal muscle ache. Stop and get medical advice the same day, as this can be a blood clot. If you are also short of breath or have chest pain, call emergency services.
A sudden pop or snap at the back of your ankle or heel, a feeling that someone kicked you there, or sudden pain there after which you cannot push off or rise onto your toes on that leg. Stop, take the weight off that leg carefully and go to an urgent care center or emergency department the same day, even if you can still walk, as this can be a torn Achilles tendon.
Pins and needles, numbness or weakness in an arm or leg that does not go away after you stop. Get medical advice the same day. If one side of your face or body suddenly goes numb or weak, or your speech becomes slurred or muddled, call emergency services, even if it goes away.
Sharp pain during an exercise, a joint that gives way, new swelling, or pain that is still worse a few days after you drop back a step. Stop that exercise and check with your physio before you do it again.

If chest pain, pressure or tightness does not ease quickly when you rest, spreads to your arm, neck, jaw, stomach or back, or comes with sweating, feeling sick, feeling light-headed or being short of breath, call emergency services straight away, as this can be a heart attack. If it eases quickly and none of these happen, get medical advice the same day, and do not exercise again until you have been checked. If you faint while exercising, call emergency services, even if you feel fine again quickly.

If you have high blood pressure, breathe steadily through every repetition and never hold your breath. The same goes for every hold, and it matters more as the load goes up. The top rungs, such as decline push-ups or added weight, are hard work. With a heart condition or high blood pressure, check with your doctor before you start.

After surgery, the timing of each step up belongs to the surgeon or the local protocol. Fitness guidelines for healthy adults do not set it. With a heart or lung condition, the medical team decides how hard the patient works. A home program supports practice between visits. It does not replace an assessment, and a change in symptoms always calls for one.

The short version

Exercise progression in physical therapy, as many physios run it, means moving one lever at a time, in small steps, toward the patient's goal. Progress when the symptoms settle by the next morning, the effort has dropped, and the movement still looks right to the last rep. Regress one step for a flare or a bad week, and stop and reassess for new symptoms. Write the current step, the next step, the step back and the rule for each into the home program, then check them at every review.
