One of the most common questions after surgery is straightforward but important: when should I start moving? The answer, for almost every procedure, is sooner than you think. Modern surgical recovery emphasises early mobilisation, getting out of bed and beginning gentle movement as soon as it is safely possible, because the evidence overwhelmingly shows that early movement leads to faster recovery, fewer complications, and better outcomes.
This does not mean pushing through pain or doing too much too soon. It means understanding that rest and movement are both essential, and that finding the right balance between them is one of the most important things you can do for your recovery.
Why early movement matters
The benefits of early movement after surgery are well documented and significant.
Reduces the risk of blood clots. Deep vein thrombosis (DVT) is one of the most serious complications of surgery. Blood clots form when blood pools in the veins of your legs during periods of immobility. Walking, even short distances, activates the calf muscles that pump blood back toward the heart and significantly reduces this risk.
Prevents muscle wasting. Muscle loss begins within 24 to 48 hours of inactivity and accelerates rapidly. The quadriceps, the large muscles at the front of your thighs, can lose measurable strength in just three days of bed rest. Losing muscle makes every subsequent task, from walking to standing from a chair, harder.
Improves lung function. Lying flat for extended periods allows fluid to accumulate in the lower parts of your lungs, increasing the risk of chest infections. Sitting up and walking keeps your lungs fully expanded and clears secretions naturally.
Stimulates digestion. The bowel slows down significantly after surgery and anaesthesia. Walking is one of the most effective ways to restart normal digestive function and prevent the constipation that affects most post-surgical patients.
Supports mental health. Being confined to bed, dependent on others, and in pain takes a genuine toll on mental wellbeing. Getting up, walking to the window, and proving to yourself that movement is possible provides a psychological boost that should not be underestimated.
Reduces swelling. Movement activates the lymphatic system, which drains excess fluid from tissues. For more on managing swelling, see our guide on how to manage swelling after surgery.
When to start
Your surgical team will tell you when it is safe to begin moving. For most procedures, this happens remarkably quickly.
Same day or next morning. After hip or knee replacement, you will typically stand and take a few steps with a physiotherapist within 12 to 24 hours of surgery. After many abdominal procedures, you will be encouraged to sit up and stand within the first day.
Within 24 to 48 hours. After cardiac surgery, spinal surgery, or more complex procedures, the timeline may be slightly longer, but movement is still prioritised as early as is safe.
As soon as the effects of anaesthesia have worn off. General anaesthesia affects coordination and balance for several hours. Once these effects have cleared and you are fully awake, movement becomes a priority.
The first movement is not about distance or duration. It is about getting vertical. Standing beside the bed for 30 seconds is a meaningful achievement on day one. Sitting in a chair for 10 minutes counts as significant progress.
What early movement looks like
Early mobilisation follows a natural progression. Each stage builds on the last.

In-bed exercises
Before you even get out of bed, you can begin exercises that reduce the risk of blood clots and maintain muscle function.
Ankle pumps. Flex your feet up and down, pushing your toes toward the ceiling and then pointing them away. This activates the calf muscles and improves blood flow in your lower legs. Aim for 10 repetitions every hour while awake.
Leg slides. Slide your heel along the bed toward your buttock, bending your knee, then straighten it again. This maintains knee range of motion and engages the quadriceps.
Gluteal squeezes. Tighten the muscles of your buttocks, hold for five seconds, and release. This activates muscles that support walking without putting stress on your wound.
Your physiotherapist will give you specific exercises appropriate for your procedure. Do them consistently, even when they feel like they are not achieving much. They are.
Sitting up
The transition from lying flat to sitting on the edge of the bed is a significant step. Use the log roll technique: roll onto your side, then push up with your arms while swinging your legs off the edge. For detailed instructions, see our guide on how to get in and out of bed after surgery.
Sit on the edge of the bed for a few minutes before standing. Let any dizziness pass. Have someone beside you for the first few attempts.
Standing
Once sitting comfortably, push up to standing using your legs and arms. Pause once upright and assess how you feel. If you are dizzy, sit back down. If you are stable, stand for a minute or two before sitting again.
Standing is itself exercise. Your muscles are working to keep you upright, and your circulatory system is adjusting to the change in position.
First steps
Your first walk will be short. A few metres along the hospital corridor with a physiotherapist beside you and a walking frame in front of you is a typical first walk after major surgery.
This is not about speed, distance, or looking competent. It is about proving to your body and your brain that you can do it. Every step after that builds on this foundation.

How much is enough?
In the first few days, the goal is frequency rather than duration. Multiple short sessions of activity throughout the day are more beneficial than one long session.
Days one to three: Stand and sit several times. Walk to the bathroom and back. Walk the length of the hospital ward if you can. Rest between sessions.
Days three to seven: Walk several times a day, gradually increasing the distance. Sit in a chair for meals rather than eating in bed. Continue your prescribed exercises.
Weeks one to two at home: Walk inside the house regularly, at least every couple of hours during waking time. Begin short outdoor walks if your team has approved it.
Weeks two to four: Increase walking distance and begin more structured exercise as your physiotherapist advises.
The right amount of activity leaves you feeling mildly tired but not exhausted. If you need to rest for more than 15 minutes after a walk, you probably did too much. Scale back the next session.
How much is too much?
The line between productive activity and overdoing it is important to respect.
Signs you are doing too much:
Significantly increased pain at the surgical site that lasts more than an hour after activity. Increased swelling that does not settle overnight. Exhaustion that prevents you from doing anything else for the rest of the day. Feeling worse overall compared to the previous day.
Signs you are doing too little:
Increasing stiffness in your joints. Constipation that does not improve with dietary changes. Persistent low mood or frustration. No improvement in stamina from one week to the next.
The balance is individual. What is too much for one person may be too little for another. Your physiotherapist can help you find the right level.
The role of rest
Early mobilisation does not mean constant activity. Rest is equally important.
Your body does its most intensive healing during sleep and rest. The cellular processes of tissue repair, immune function, and inflammation management all require energy, and that energy comes from rest.
The ideal pattern is alternating periods of gentle activity with periods of rest. Walk for five minutes, rest for an hour. Walk again, rest again. Gradually, the ratio shifts as you get stronger, but rest remains essential throughout the recovery period.
Overcoming the fear of movement
After surgery, it is entirely normal to be afraid of moving. You fear pain. You fear damaging the surgical repair. You fear falling. These fears are valid, and they are also, in most cases, worse than the reality.
Your surgeon has repaired the area so that it can withstand the forces of normal activity. The physiotherapy exercises you have been given are specifically designed for your stage of recovery. Your walking aid provides support that your body cannot yet provide itself.
The first step is always the hardest. The second is easier. By the tenth, you will wonder what you were worried about.
Creating a daily routine
Structure helps. In the first few weeks at home, a simple routine gives your day shape and ensures you are moving enough.
A reasonable pattern might include: exercises in bed after waking, a walk to the kitchen for breakfast, a rest, a short walk mid-morning, lunch, a rest, afternoon exercises, a short walk, dinner, and a gentle walk before bed.
This does not need to be rigid. Adapt it to how you feel each day. The point is to build regular movement into your day so it becomes habit rather than something you have to motivate yourself to do.
Movement after surgery is not something your body has to earn. It is something your body needs. Each small effort builds toward the strength and independence that recovery is all about.
