Question

Which ab exercise is better? situps or crunches ? Why ?

Answer 1

Crunches work the upper abs. Sit ups work upper and lower abs, but not as efficient. Leg raises work lower abs.

For example:

Crunches - 100% upper abs

Sit ups - 50% upper abs and 50% lower abs

Leg raises - 100% lower abs

(They work out various other small muscles, but not significantly)

Basically, do them all, if you can. Personally, I alternate between crunches and leg raises, but I'm working them hard. If you do 20 of each a day, it won't make a difference.
