Best way to do sit ups to burn fat.......?

[ShiftBone]

I'm a boxer and I do like at least 300 situps/crunches a day....it's good for
burning fat off your stomach...i'm just wonderin what tha best way to make your abs
burns...but shape em at tha same time...like what position?

First of all, doing
sit-ups does not burn fat. There is no such thing as spot reducing, so u can forget that. 300
situps a day? I dont see how that will help u out in ur boxing career, u wanna work ur whole
core since that is where most of ur power in boxing comes from anyways. U also wanna work
on ur lower back, and legs.
