Work the sides of your abs.
Lie back on a mat with knees bent, arms at your sides, and palms facing body. Raise your head and shoulders a few inches off the floor, making sure to keep your chin off your chest. Next, reach toward your ankles (you won’t be able to make contact) in a little pulse, raising your head and shoulders another couple of inches off the mat. Hold for one count, and return to starting position. Perform two sets of 10 to 12 repetitions.
