Purpose
- ab builder curling your hips towards your chest rather than your chest towards
your hips
- the pelvis is what moves, so the abs shorten the spine from the bottom end: a
sit-up works the same muscle from the other direction
- it is the leg-raise pattern done as actual spinal flexion, which is what a leg
raise stops short of
Execution
Lie on your back with your knees bent and your hands by your sides or under your
hips. Start with your thighs vertical.
- curl your hips off the floor, bringing your knees towards your chest
- let your lower back round as your pelvis tilts under
- stop when your hips leave the floor rather than rolling onto your upper back
- lower under control until your lower back touches down
- keep the movement in your pelvis rather than swinging your legs
Slow the lowering down. Dropping the hips back is what turns this into a leg
swing.
