Diastasis recti: what you can actually train

How to measure diastasis recti, which exercises you can start today, what to pause and when to see a doctor - with concrete sets, reps and timelines.

Diastasis recti is a widening of the gap between the left and right halves of your rectus abdominis, caused by the connective tissue down the middle of your belly (the linea alba) stretching out. It shows up most often after pregnancy, but you also see it in men carrying a large waist. The good news: almost everything is still on the table — the question is what order you do it in and how well you control pressure inside your abdomen.

Measure first, then plan

The self-test takes a minute:

Lie on your back, knees bent, feet flat on the floor.
Place the fingers of one hand across the midline of your belly, right at the navel.
Lift your head and shoulders 2–3 cm off the floor — just enough to feel the abs engage.
Note how many fingers fit into the gap and how deep they sink. Repeat 5 cm above and 5 cm below the navel.

Up to 2 fingers is normal. 2–3 fingers is mild, over 3 fingers is moderate to significant. But the finger count is not the headline number. What matters more is whether you feel tension under your fingers when you lift, or whether your hand sinks into a soft bag. Tissue that tightens under load is doing its job even if the gap is three fingers wide.

Rule one: watch your belly, not your rep count

If a ridge pops up along the midline during an exercise — a small tent running up from the navel — the pressure is higher than the tissue can currently handle. That ridge is your stop signal, not pain. Pain shows up far too late to be useful here.

In practice: do your first 2–3 sessions in front of a mirror or with a hand on your stomach, and judge every exercise on three things — can I breathe normally, does the midline dome up, is there downward pressure in the pelvis. If any answer is bad, cut the range of motion or the load by 30–50 % and re-check.

What you can do right now: weeks 1–6

Rib breathing — on your back, hands on the lower ribs. Inhale 4 seconds so the ribs widen sideways, exhale 6 seconds. 3 sets of 10 breaths, daily.
Exhale with a gentle draw-in — on the exhale pull the lower belly in like you are doing up tight trousers, about 30 % of max effort. 3×10, hold 3 seconds.
Heel slides — one leg straightens along the floor while the trunk stays still. 3×8 per leg.
Dead bug, knees bent — lower one leg only, 3 seconds down, 3 seconds back. 3×8 per side.
Glute bridge — 3×12 with a 2-second hold at the top.
Side plank from the knees — 3×20–30 seconds per side.
Walking — 20–30 minutes a day at a normal pace.

That is 15–20 minutes, 4–5 times a week. Unglamorous, but this block builds the control that everything later depends on.

Progression: weeks 6–12

Once you get through two straight weeks of the above without a single ridge, add:

Dead bug with the leg fully extended — 3×8 per side.
Bird dog — 3×8 per side, 3-second hold.
Pallof press with a light band — 3×10 per side, exhale through the hardest part.
Side plank from the feet — 3×30 seconds.
Suitcase carry — 3×30 metres with 12–20 kg, trunk quiet, shoulder not dropping.

The gym: what stays on the list

There is no reason to drop strength work — it is part of the fix. Squats, leg press, Romanian deadlifts, rows, overhead press and all upper-body work stay in. Work in the 8–12 rep range with 3–4 reps left in reserve, and exhale through the hardest part of the lift instead of holding your breath.

The loading rule is simple: stay at a weight you can handle without breath-holding until your face goes red and without any doming. If either shows up, drop 20 % and try again next week.

What you pause for now

Standard crunches, sit-ups, V-ups, flutter kicks and double leg raises.
Front planks longer than 20 seconds, if a ridge appears.
Weighted Russian twists and fast loaded rotation.
Kipping pull-ups and explosive overhead work.
One-rep-max attempts and anything that forces a 5+ second breath hold.

None of this is a life sentence. Most people are back to direct ab work and heavy lifting within 3–4 months of consistent work — just in a different order than they would have chosen alone.

Running and jumping: when

Clear four criteria before you add impact: 30 minutes of brisk walking with no symptoms, 10 single-leg glute bridges per side, 30 seconds standing on one leg, and zero leaking when you cough, sneeze or hop. Once you have that, start with 1 minute running / 2 minutes walking for six rounds, twice a week.

Food and bodyweight, briefly

No food closes a diastasis. What helps is enough protein for tissue repair — 1.6–2.0 g per kilogram of bodyweight per day — and a gradual reduction in fat around the waist, since every kilogram less means less pressure pushing outward. If you are breastfeeding, do not go below roughly 1,800 kcal and aim for 0.3–0.5 kg a week, no faster.

When to see a doctor

A hard or painful bulge that does not settle when you lie down — that can be a hernia, and exercise will not fix it.
A gap over 5 cm, or no change at all after 12 weeks of consistent work.
Leaking urine or stool, or a sensation of something bearing down in the pelvis.
Low back or pelvic pain lasting more than 2 weeks that is not easing.
Severe pain around the navel with nausea or vomiting — that is same-day urgent.

A pelvic floor physiotherapist is not mandatory, but one appointment usually saves months, because they can assess what you cannot see in a mirror.

The short version

Measure at three points, but tissue tension tells you more than the finger count.
A ridge down the midline is your stop signal — not pain.
Weeks 1–6: breathing, dead bugs, bridges, side planks, walking — 15–20 minutes, 4–5 times a week.
Strength training stays: squats, deadlifts, presses, with an exhale and 3–4 reps in reserve.
See a doctor for a hard bulge, leaking, or zero progress after 12 weeks.
