You go for the six-week check, the GP says things look fine, and somewhere in the back of your mind you expect to feel ready to move again. Sometimes you do not. Or you do feel ready, and then a short walk leaves you with a heaviness low down that was not there before. Returning to exercise after birth is rarely as simple as one appointment suggests, and the gap between being told you have recovered and actually feeling it in your body can be wide. The six-week mark is not a starting gun. It is one point in a longer process that looks different for everyone.
In the UK, you are offered a postnatal check with your GP at six to eight weeks to look at how your body and mind are recovering. If you have not had this appointment yet, it is worth calling your GP or midwife to arrange it. The check matters, though it works more as a conversation starter than a green light for everything. The guidance here fits a straightforward recovery. If you had a caesarean section, an assisted delivery, significant perineal tearing, or any complications during birth, talk through your return to movement with your GP, midwife, or a pelvic health physiotherapist before following general timelines.14
Walking as the foundation for returning to exercise after birth
Walking is a good place to start. After a straightforward vaginal birth, you can begin short, gentle walks as soon as you feel able. Gentle is the key word. A ten-minute walk at an easy pace is a real starting point, and there is no rush to make it longer.2
As you walk, pay attention to how your body responds. A heaviness or dragging feeling in your pelvis, any leaking of urine, or discomfort in your perineum or lower belly are all signs to slow down or stop. These sensations are your body telling you about load, and they are worth listening to rather than pushing through. Build up distance and pace slowly, and only once shorter walks feel comfortable both during and afterwards.3
Starting with your pelvic floor
Before any other structured movement, pelvic floor exercises come first. Your pelvic floor is a group of muscles at the base of your pelvis that support your bladder, bowel, and uterus. Pregnancy and birth put these muscles under real strain, and working with them early supports your recovery and helps with bladder control.
You can start pelvic floor exercises within days of birth, once you have passed urine without concern and feel able. To find the right muscles, you can picture the feeling of trying to stop passing wind and stopping the flow of urine. That is a teaching cue only. Do not actually try it while urinating, since that can get in the way of normal bladder function. Once you can feel the right muscles, practise the gentle squeeze and lift away from the toilet.4
If you notice any leaking of urine, or a feeling of heaviness, dragging, or bulging in the vagina during or after exercise, stop and get advice from your GP or a pelvic health physiotherapist. These sensations can mean the pelvic floor is being overloaded, and in some cases they point to pelvic organ prolapse, which needs a proper assessment. They are worth taking seriously.5
How do breathing exercises help with recovery?
Breathing exercises can begin within hours of birth. Keep it easy and unforced. You are simply reconnecting with the natural rhythm of your breath, letting your belly soften and move with it.6
From there, you can introduce gentle core work early on. One example is drawing your lower belly gently in towards your spine as you breathe out. This is a low-intensity way to reconnect with the deep abdominal muscles that support your spine and pelvis. If you had a caesarean section, follow the specific post-operative guidance from your clinical team before starting any core work, even at this gentle level.7
What the body signals when it is not ready
Your joints and ligaments can feel looser for a while after birth. That comes down to the hormonal changes of pregnancy, as well as reduced muscular strength as a result of reduced activity that can be true for many in pregnancy. It means your body is more open to injury from sudden jumps in load or intensity, even on days you feel well.1
Some symptoms are clear signs to stop exercising and get medical advice: abdominal pain, heavier vaginal bleeding, or difficulty walking. Two need more urgent attention. Calf pain can be a sign of a deep vein thrombosis (DVT), a blood clot in the leg, which is more likely in the weeks after birth. A severe headache that will not shift can be a sign of pre-eclampsia, a serious blood pressure condition. If either of these happens, call NHS 111 straight away or go to A&E. Do not wait.8
How diastasis recti affects the timeline
During pregnancy, the connective tissues between rectus abdominus muscles, that run down the centre of your tummy, thins and widens, allowing the muscles to move apart to create more space for your growing baby. This is called diastasis recti, or abdominal muscle separation, and some degree of it is a normal part of pregnancy. For many, the gap closes on its own in the first 6-8 weeks after birth.9
If you can still feel a gap, or you notice a dome or ridge appearing down the centre of your belly when you lift your head or legs, it is worth raising with your GP or physiotherapist. If the gap is still there at eight weeks after birth, a clinical assessment is a good idea. Some exercises, particularly sit-ups, crunches, and full planks, can make the separation worse, so they are best avoided if you have suspected or confirmed diastasis recti.10
What to hold off on, and for how long
High-impact activities like running, aerobics, or jumping put a lot of load through your pelvic floor and connective tissue. These are best left until at least 12 weeks after birth, and guidance suggests waiting three to six months before a gradual return. Twelve weeks is the earliest starting point. The right timing depends on your symptoms, how your pelvic floor is working, and ideally some input from a pelvic health physiotherapist.11
Swimming is something you may feel ready to come back to fairly early on. You can go back to the pool once postnatal bleeding (lochia) has been completely gone, around 6-8 weeks. If you had a caesarean section, check with your surgical or midwifery team first, since wound healing matters beyond the bleeding stopping.12
For the first six weeks, it helps to avoid lifting anything heavier than your baby. When you do lift, bend your knees and keep your back straight rather than bending from the waist. If you had a caesarean section, your lifting restrictions may be more specific, and your clinical team can advise on these.13
Recovery does not move in a straight line
A day that feels manageable does not mean you can suddenly do more. Postnatal recovery moves in waves, and your body's readiness for movement shifts with sleep, feeding, healing, and stress. Letting your symptoms guide you, rather than a fixed timeline or a target to hit, tends to be more reliable than any calendar.
If you are not sure where you are in your recovery, or any symptoms come up when you start moving again, a referral to a pelvic health physiotherapist is a practical next step. You can ask your GP for a referral, or self-refer in many areas.
