ab builder raising your legs from the floor, with peak tension where the abs
are longest
with your legs low the lever from your hips is at its longest, so the hardest
part of the rep is the bottom: the hanging version has nothing there
past vertical it becomes hip flexor work, so the range that matters is the
first half
Execution
Lie on your back with your legs extended and your hands under your lower back or
lightly on the floor. An ab mat under your lower back deepens the bottom
position.
start with your legs lowered towards the floor
hold a slight posterior pelvic tilt throughout
raise your legs by flexing at the hips until they are vertical
lower them under control, fighting hardest near the floor
stop before your lower back lifts off
The bottom is the whole exercise. When the set gets heavy, bang out a few more
reps in the bottom half to milk the stretched position.
