Sit-ups or crunches?

[Sock-Puppet]

ok, so, what is better..situps or crunches?
is one better for boxing?
and is one better for developing abs?
and what's a good rep/set( im still confused on which is a rep and which is a set)... 2x15 ...?

Neither if you are fat as me.....first I need to burn fat.

I say sit ups for over all results unless you just want to look pretty and be a soft as a g****.

sit ups blow, they're bad for your back, do crunches son, it's the only thing that can tone up my fat gut after a night of heavy drinkin and rib eatin

crunch's thats an easy question

situps, at a decline, I do like 2 sets of 100 before i leave my boxing club

situps bnecause they work your full stomach muscles.. crunches only work well for your upper stomach, situps for midsection and corkscrews for lower stomach. If you want a full abdominal workout you should do all 3.

Situps are proven to be bad for your back and neck.
Crunches are alot better.

Personally I do weighted crunches with like a cushiony thingy under my lower back..
Discs in my back dig into the floor not the best feeling..

crunches are great. You should also try leg raises, they work the lower part of the stomach, the part that some of us hate to work.
