your feet are anchored, so the hip flexors help through the second half and
the abs own the first: the part that matters is getting your shoulders off the
floor
the floor stops your spine at neutral, so there is no extension to work
through, which is what the decline version adds
Execution
Lie on your back with your knees bent and your feet flat on the floor, hands
across your chest or behind your head.
curl your shoulders off the floor, rounding your spine as you rise
keep curling until your torso is upright
lower under control, unrolling your spine on the way down
let your shoulders touch down before the next rep
keep your hands light rather than hauling on your head
Add load by holding a plate against your chest rather than by speeding up.
