When to start postnatal exercise, what's safe at each stage and the signs to stop. A practical guide from TNT Fitness in Cowan Bridge, near Kirkby Lonsdale.
You've had your baby, and somewhere between the night feeds and the nappy changes you've started to miss feeling like yourself. You want to get strong again, but you've no idea what's safe, when to start or whether that twinge means you're doing too much.
This guide walks through postnatal exercise one stage at a time, and explains how Anna Anyon, our pre- and postnatal specialist at TNT Fitness in Cowan Bridge, near Kirkby Lonsdale, can help. It's general guidance, not medical advice, so always follow what your GP or midwife tells you.
The Short Version
- Pelvic floor exercises and gentle walking can usually start soon after birth, if you feel up to it.
- Wait for your postnatal check, usually six to eight weeks after birth, before starting anything more structured.
- Rebuild your core and pelvic floor before you add impact, like running or jumping.
- Recovery after a caesarean usually takes longer. Check with your GP before returning to exercise.
- Leaking, heaviness, pain or bleeding are signs to stop and get checked, not to push through.
Every Recovery Is Different
There's no single timeline for getting back to exercise after having a baby. The type of birth, how your pregnancy went, how much you trained beforehand and how much sleep you're getting all play a part.
So compare yourself to nobody. The aim is to rebuild steadily, not to "bounce back" by a certain date.
Stage 1: The First Six Weeks
This stage is about recovery, not fitness. Focus on:
- Pelvic floor exercises. The NHS recommends starting these as soon as you feel able after birth. Gentle squeezes and lifts, little and often.
- Breathing. Slow, deep breaths that let your ribs and tummy expand, then gently draw in as you breathe out. It's the foundation of reconnecting with your core.
- Walking. Short, gentle walks with the pram, building up gradually as you feel ready.
If you had a caesarean, you're recovering from major surgery. Follow the advice you were given in hospital, and don't lift anything heavier than your baby until you've been told it's safe.
Stage 2: After Your Postnatal Check
Your postnatal check with your GP usually happens six to eight weeks after birth. It's a good moment to ask whether you're ready to start exercising more, and to mention any symptoms like leaking or pain.
Once you've had the go-ahead, this stage is about low-impact strength. That might include:
- Glute bridges and side-lying leg work
- Squats to a box or bench
- Supported rows and presses with light weights
- Gentle core work that keeps your tummy flat rather than bulging or "doming"
Your body has done something huge, so start lighter than you think you need to.
Stage 3: Building Back Strength and Impact
As your strength and pelvic floor recover, you can gradually add more load and, eventually, impact.
Running and jumping put a lot of demand on your pelvic floor. Widely used UK return-to-running guidance, written for health and fitness professionals in 2019, suggests waiting until at least around 12 weeks after birth before running, and only if you have no symptoms.
A sensible order to build back in:
- Strength exercises with steadily heavier weights
- Low-impact cardio, like the bike, rower or brisk walking
- Short, controlled impact, like marching on the spot into gentle jogging
- Running, building time very gradually
If symptoms appear at any stage, drop back a step and get checked.
A Gentle First Gym Session After Your Check
Once you've had the go-ahead, a first session might look like this. Keep the effort comfortable, and stop if anything feels wrong.
- Warm up, 5 minutes: easy bike or brisk walk on the treadmill.
- Breathing and pelvic floor, 3 minutes: breathe in to let your ribs expand, then breathe out as you gently lift your pelvic floor.
- Glute bridge, 2 sets of 10.
- Box squat to a bench, 2 sets of 8.
- Supported dumbbell row, 2 sets of 10 each side.
- Side-lying leg lifts, 2 sets of 10 each side.
- Cool down: a short walk and some gentle stretches.
Notice how you feel that evening and the next day. If everything feels fine, you can add a set or a little weight next time.
Signs to Stop and Get Help
Speak to your GP, or ask for a referral to a pelvic health physiotherapist, if you notice:
- Leaking when you cough, laugh, lift or exercise
- A feeling of heaviness or dragging in your vagina
- Pain in your pelvis, back or caesarean scar
- Bleeding that gets heavier or returns after exercise
- A ridge or "dome" down the middle of your tummy when you lift your head or sit up
These are common after birth and can often be helped a great deal. They're not something you just have to put up with.

Fitting Training Around a Baby
Some honest, practical tips:
- Short sessions count. Twenty focused minutes beats an hour you never get round to.
- Train when you can. We're open 5am to 10pm every day, so early mornings, nap times and evenings all work.
- Sleep comes first. On a night of very little sleep, a walk might be better than a hard session.
- Eat enough. Especially if you're breastfeeding. Recovery needs fuel, so this isn't the time for crash diets.
Frequently Asked Questions
When can I start exercising after giving birth?
Pelvic floor exercises and gentle walking can usually start soon after birth if you feel up to it. For anything more structured, wait for your postnatal check, usually six to eight weeks after birth, and follow your GP's advice.
Is it different after a caesarean?
Yes. A caesarean is major surgery, and recovery usually takes longer. Follow the advice you were given in hospital and check with your GP before returning to exercise.
When can I start running again?
Widely used UK guidance for professionals suggests waiting until at least around 12 weeks after birth, and only if you have no symptoms like leaking, heaviness or pain. Build strength first, then add impact gradually.
Can I do sit-ups after having a baby?
It's best to rebuild your deep core first. If you see your tummy doming or bulging during an exercise, it's too much for now. A postnatal specialist can show you what to do instead.
