The reverse crunch (using the slant board) – with your hand holding the bars and your legs straight on the floor, raise your knees to your face, while bending your knees, until the fetal position. Then slowly drop your rear end until you touch the board and repeat the exercise.
Leg lifts (performed on the Roman Chair) – Start with your back on the back support and lift your knees/legs to its highest point. Feet should not be allowed to swing behind your rear end at its lowest point for safety and momentum purposes.
Hanging leg raises (performed on the cable machines) – Start by hanging from the middle pull up bar on the cable machines. The hanging leg raise is probably the most result producing stomach exercise since it is generated from the lower abs and then incorporated the upper abs at its peak. It begins by having your feet lift over and above your waist until it reached approximately where your hands are holding on. Remember to keep you body from swinging back and forth. This will cause you to use more stomach muscles and less momentum.
Then proceed to your upper/middle abs to get that desired burn.
The Ab Roller, which is great for upper abdominals and obliques, is great to start with since it promotes safety and immediate results. Exercises utilizing the ball and floor mats are great ways to end a stomach workout. The utility ball allows for maximum stretching to hit all areas of the mid-section.
