Bingo. For guys, abs are all about body fat - if you're not pushing down towards single digit BF%, you can flat out forget the six pack. The belly fat is pretty much the last to go for us guys, so that's just the way it is.You can't spot reduce fat. You lose fat in layers throughout your body. To have defined abs you'll need to drop your body fat down to an extremely low level.
Jumping exercises are good to get rid of stomach fat - squat jumps, box jumps, lunge jumps, and broad jumps are some of the best ways to incorporate explosive jumping exercises into your routines. The explosive and powerful nature of jumping exercises works your leg muscles in an entirely different way than most normal slow grinding strength training moves. I've even seen a university study cited once that found squat jumps to elicit the greatest testosterone response of all exercises studied.
