Postnatal exercise contraindications are poorly served in general fitness training, which is why patients so often arrive having been given a programme that was never appropriate. This is a screening and prescribing guide for UK physiotherapists, midwives and practitioners taking postnatal referrals, covering absolute red flags, relative cautions and the movements worth deferring.
TL;DR
- Screen for red flags before prescribing anything, not at the first review.
- Absolute contraindications are largely obstetric and need onward referral, not modification.
- Most of what you will see is a relative caution, meaning defer and regress rather than exclude.
- Doming and leaking are the two functional signals that should drive your dosage.
- Caesarean is abdominal surgery, so abdominal loading waits regardless of how well the patient feels.
- Breath holding under load is the mechanism behind most avoidable setbacks.
Screening before prescription
A short structured screen at the first appointment saves a great deal later. The questions that change management most:
- Mode of delivery, and any instrumental assistance or significant tearing.
- Whether the postnatal check has happened and what was said.
- Any leaking of urine or faeces, urgency, or incomplete emptying.
- Any heaviness, dragging or a sensation of something coming down.
- Bleeding: has lochia settled, and has it restarted at any point.
- Pain, its location, and whether it is easing or worsening week to week.
- Wound status where there has been a caesarean or repair.
- Feeding, sleep and fatigue, which affect tolerance more than most programmes account for.
Absolute contraindications: refer, do not modify
- Heavy or restarting vaginal bleeding, or passing clots.
- Signs of wound infection: spreading redness, heat, discharge, dehiscence, systemic fever.
- Suspected venous thromboembolism, including unilateral calf pain and swelling, chest pain or breathlessness.
- Suspected postpartum pre-eclampsia, including severe headache, visual disturbance or new significant hypertension.
- Undiagnosed pelvic or abdominal pain that is severe or worsening.
- Signs of postpartum sepsis.
These are onward referral, urgently, and exercise is not the conversation. The NHS caesarean guidance and RCOG cover the obstetric picture.
Relative cautions: defer, regress, review
- Caesarean within six weeks. No abdominal loading. Walking, breathing and pelvic floor work only, and later if recovery has been complicated.
- Third or fourth degree tear. Pelvic floor work should be guided rather than generic, and impact deferred considerably.
- Symptomatic prolapse. Avoid loaded deep squats, heavy lifting and impact while symptomatic. Pelvic floor training is first line per NICE NG123.
- Diastasis with uncontrolled doming. Regress until the midline stays flat. Doming is dose information, not damage.
- Pelvic girdle pain. Avoid wide-legged and single-leg loading while symptomatic. Ball squeezes are usually well tolerated.
- Any leaking during a movement. Reduce the load or impact. Leaking is a signal the pressure system is not managing.
- Significant fatigue or anaemia. Tolerance is genuinely reduced and programmes fail on this more often than on technique.
Movements worth deferring in the early phase
- Sit-ups, crunches and any loaded trunk flexion.
- Double leg lowers and V-sits.
- Full plank, until an incline version can be held with a flat midline.
- Loaded deep squats where prolapse symptoms are present.
- Running and jumping, until pelvic floor function supports it.
- Any lift performed with a breath hold.
What replaces them is unglamorous and effective: connection breathing, glute bridges with a ball squeeze, side-lying abduction against a light loop, heel slides, and progressive walking. Our latex-free resistance loops from £2.49 ex VAT and small exercise balls at £6.66 ex VAT cover the whole early phase, and volume pricing applies for clinic ordering.
The two signals that should drive your dosage
Doming. If the midline cones during effort, the load exceeds what it can transfer. Regress the movement until it does not, then progress from there. It is the most useful real-time feedback available and it costs nothing.
Leaking. Any leak during an exercise means the pressure system failed at that dose. Reduce it rather than coaching harder, and reassess pelvic floor function before returning to impact.
Both are more informative than a finger-width measurement, and both can be taught to the patient so they self-regulate between appointments.
Where clinicians most often go wrong
- Treating six weeks as a return to previous activity rather than the start of rehabilitation.
- Prescribing pelvic floor strengthening to a patient whose pelvic floor is overactive, where symptoms overlap and squeezing worsens them.
- Programming abdominal work before pressure management is established.
- Not asking about leaking, which patients frequently will not volunteer.
- Giving a home programme without giving the equipment, then reviewing a programme that was never done.
That last one is a supply problem rather than a clinical one, and we have covered the economics in patient take-home exercise kits.
FAQs
What are the absolute contraindications to postnatal exercise?
Heavy or restarting bleeding, signs of wound infection, suspected venous thromboembolism, suspected postpartum pre-eclampsia, signs of sepsis, and undiagnosed severe or worsening pelvic or abdominal pain. These require onward referral rather than a modified programme.
When can a postnatal patient start abdominal loading?
After clearance, typically at the six to eight week postnatal check, and later following a caesarean or a complicated recovery. Start with pressure management and connection breathing, then heel slides, progressing only while the midline stays flat.
Is doming a reason to stop the exercise?
It is a reason to regress it, not to stop. Doming indicates the load exceeds what the linea alba can transfer at that moment. Reduce range or leverage until the midline stays flat, then progress. Framing it as damage causes unnecessary fear and avoidance.
Should every postnatal patient do pelvic floor strengthening?
No. An overactive pelvic floor produces overlapping symptoms and worsens with strengthening. Assess before prescribing, and consider down-training where there is pain, difficulty emptying or symptoms that increase with contraction work.
How soon can a postnatal patient return to running?
Commonly three to six months, and it should be driven by pelvic floor function and load tolerance rather than a date. Leaking or heaviness on impact testing indicates more base work is needed first.
What equipment is appropriate for early postnatal rehabilitation?
Light resistance loops, a small exercise ball for deep core cueing and a cut length of flat band cover almost the entire early phase. Weight your stock towards the lighter strengths, since this caseload starts considerably lighter than general musculoskeletal work.
Conclusion
Screen first, refer the red flags, and treat almost everything else as a dosage question rather than an exclusion. Doming and leaking will tell you more about the right load than any measurement, and both can be handed to the patient to self-monitor.
For clinic stock, our latex-free loops and band rolls cover the early phase at volume pricing. If a patient would rather buy a ready-made set themselves, our consumer brand sells a five-piece postnatal recovery kit for £14.99.
