First, the honest bit — same as always: no exercise burns fat off one chosen spot, and anyone promising a flat lower belly from ten minutes of leg raises is at it. What this workout genuinely does is strengthen the muscles below your belly button, the ones that steady your pelvis and back you up every time you stand, lift or carry.
It runs as a pyramid: the work climbs from 20 seconds to a 40-second peak, then comes back down. You meet the hardest move in the middle and finish on the gentlest one — a nice unwinding stretch for your back.
All five moves are done lying down, no equipment, with a video of me demonstrating each one right here on the page.
How to use this workout
The one rule for every move: keep your lower back gently pressed towards the floor. The moment it arches up, bend your knees more or shrink the movement — smaller and controlled always beats bigger and swinging.
The workout
How it should feel — and when to make it harder
A deep, slightly trembly effort low in your belly is the target; a complaining lower back is the signal to shrink the range. The peak should be honest work and the final scorpion kicks should feel like a treat. When two rounds feel steady, slow the lowering phase of every rep — that's where the strength lives. And if you've got a health condition or you're on medication, have a quick word with your GP before you start — costs nothing, buys peace of mind.
Prefer a flat, steady version? My lower belly core workout runs the classic 30-seconds-a-move format.
Quick questions
Why do lower ab moves feel so much harder?
Because modern life never uses those muscles — sitting all day does nothing for them. They're not weak because something's wrong with you; they're weak because they're untrained. That changes quickly.
Will this flatten my lower belly?
On its own, no — and I'd rather be straight with you than take the click. It strengthens what's underneath, which improves how you stand and move. How your middle looks changes with months of consistency, not minutes of leg raises.
What if my back arches off the floor?
Shrink the move — bend your knees more, lower your legs less far, or swap to the easiest variation for that slot. A pressed-down back doing half the range beats an arched back doing all of it.
