After your operation
Arm and shoulder exercises after breast surgery, step by step
Exercises usually start the day after surgery, with gentle movements building over the following weeks. The aim is to get your arm comfortably above your head again, and little and often works far better than one determined session. This page sets out the programme stage by stage, and why the timing matters so much.
The short answer
Which exercises, and when do I start?
Usually the day after surgery, starting with gentle movements and building over the following weeks. The aim is to get your arm comfortably above your head again. Little and often works far better than one determined session.
Why it matters more than it sounds
A shoulder that is not moved tightens within days, and the scar tissue matures in that shortened position. Getting the range back later is a much longer job than keeping it. This is the single most useful thing you can do for yourself in the first fortnight.
There is a practical deadline
Radiotherapy needs your arm raised and held above your head, still, for several minutes. If you cannot reach that position comfortably when planning starts, treatment can be delayed. That is a concrete target to work towards.
Follow your own instructions first
Some operations, particularly reconstructions using your own tissue or muscle, come with specific restrictions for a set period. Where your team's advice differs from anything here, theirs applies.
Take a simple painkiller half an hour before exercising. Being on top of pain is what lets you do them properly.The programme
Building up, stage by stage
Shoulder rolls and shrugs
Sitting or standing, roll the shoulders slowly backwards, then shrug up and release. Start the day after surgery. This wakes the joint up without stretching the wound.
Elbow and hand movements
Bend and straighten the elbow, open and close the hand, rotate the wrist. These keep circulation moving in the whole limb and reduce swelling, and they are safe from the first day.
Walking the hand up a wall
Face a wall, walk your fingers up as far as is comfortable, hold, then walk down. Mark the height with a pencil once a week so you can see the progress.
Reaching out to the side
Turn side-on to the wall and walk the hand up sideways. This is usually the harder direction after armpit surgery and the one that matters for radiotherapy positioning.
Hands behind the head and behind the back
Once the wound has healed. Clasping the hands behind the head and reaching up the back restore the last of the range and are the movements daily life actually needs.

What makes the difference
The technique matters less than the frequency and staying just inside the point of pain.
Little and often
Three or four short sessions a day beats one long one. The joint responds to being taken through its range repeatedly rather than to one hard stretch.
Warmth first
After a warm shower is the easiest time. Tissue lengthens more willingly when warm. Be careful with heat packs on numb skin, which burns without warning.
Test any heat with your other hand.Stretch to tightness, not to pain
A pulling sensation is what you want. Sharp pain means you have gone too far. Hold at the point of tightness rather than bouncing or forcing.
Keep going after you feel better
Stiffness returns during radiotherapy as tissue tightens. Most teams advise continuing for months, not weeks. Stopping early is the commonest reason a recovering shoulder goes backwards.
Stop and ask if
- The wound starts leaking
- Swelling increases sharply
- Pain is worsening rather than easing

Words you will hear
The vocabulary, in plain language
- Range of movement
- How far the joint moves in each direction. What your physiotherapist measures to track progress.
- Abduction
- Raising the arm out to the side. Usually the hardest direction after armpit surgery, and the one radiotherapy needs.
- Flexion
- Raising the arm forwards and up. Generally recovers before abduction does.
- Cording
- Tight bands from the armpit down the arm. Common, and it responds to exactly these stretches.
- Guarding
- Unconsciously holding the arm still to protect it. The main reason shoulders stiffen early.
- Progressive loading
- Building strength back gradually once movement has returned. The later stage of rehabilitation.
Being straight with you
What to expect, and when to get help
Most women regain full or near-full movement within a few months of doing these consistently. Progress is not linear, and it slows during radiotherapy. Judge yourself week to week rather than day to day.
Some days will be worse
Tiredness, a poor night, or simply having done more than usual all show up as a stiffer shoulder the next morning. That is not a setback and it is not damage. Return to the same exercises rather than stopping for a few days.
Ask for physiotherapy sooner than you think
If movement is not improving week on week, if you cannot get the arm overhead, or if there is cording, that is the point to ask. Early referral prevents a much longer problem, and you should not have to wait until it is severe.
What this page cannot replace
It cannot replace the specific programme your team gave you, particularly after reconstruction where restrictions vary by technique. Use this to understand why the exercises matter, and follow your own instructions for exactly what and when.
Commonly believed
What families say about moving the arm
This is the most damaging well-meant advice after breast surgery. The shoulder tightens within days of not being used, and the scar matures in that shortened position. Gentle movement from the day after surgery is what prevents months of trouble.
The prescribed exercises are designed around the wound and do not put it under tension. What you avoid is lifting, pushing and carrying, not movement itself. If the wound starts leaking, stop and ring, but that is uncommon.
A pulling, stretching discomfort is expected and necessary. Sharp pain means you have pushed too far. Taking a simple painkiller beforehand is part of the treatment, and it is what lets most women do the exercises properly.
Dressing needs far less range than radiotherapy positioning does, and stiffness returns during treatment. Most teams advise continuing for months. Stopping at the point of feeling normal is the commonest reason progress reverses.
Questions we are asked
Common questions about exercises
How many times a day should I do them?
Three or four short sessions is the usual advice, each only a few minutes. Frequency matters far more than duration, because the joint responds to being taken through its range repeatedly. One long daily session is much less effective.
Can I exercise with a drain still in?
Gentle movements usually yes, and your team will say which to hold off. Secure the bottle to your clothing so it cannot pull on the tube. Do not stop moving altogether simply because a drain is present.
What if I had reconstruction?
Follow your own instructions, which are usually more restrictive for a period, particularly with flaps using muscle. Your team will tell you when to progress. Ask specifically what you may and may not do, since it varies by technique.
When can I lift my grandchild or carry shopping?
Usually after a few weeks, and later after a mastectomy, armpit clearance or reconstruction. Build up gradually rather than testing yourself with the heaviest thing. Ask your team for a weight limit and a timeframe for your operation.
Is swimming allowed?
Once the wound is completely healed and your team agrees, and it is excellent for the shoulder. Do not swim with an open wound, a drain in place, or during a wound infection. Start with short gentle sessions.
Do these exercises prevent lymphoedema?
Keeping the arm moving helps drainage and is generally encouraged, though no exercise programme removes the risk. Report any persistent swelling, heaviness or tightness early, because that needs its own assessment.
My arm is fine. Do I still need them?
Yes, particularly before radiotherapy, which requires holding the arm overhead. Range can be adequate for daily life and still not enough for treatment positioning. Keep going until your team tells you to stop.
Can I do yoga or go back to the gym?
Usually yes, gradually, once healed and with your team's agreement. Avoid heavy overhead loading early and build back rather than resuming your previous level. Tell the instructor what surgery you have had.
