Crunches

Flat abs
Lay down on a mat on the floor, bending your knees slightly so your feet are flat on the floor. Curling your hands behind your head, slowly lift your shoulders off the mat, squeezing your abdominal muscles with each raise.
Be sure not to pull your neck upwards; rather, make it a natural, smooth-flowing motion. Lift only your shoulder blades off the mat and hold that position for a span of two seconds before slowly releasing the shoulders back to the mat.
Be sure not to let your shoulders completely rest on the mat before beginning your next repetition. Do three sets of 30 reps, taking only a few seconds of rest between sets.
