Sets: 1-2 Reps: 15 Tempo: 111 Rest: 0 Seconds
Lie on your back on the floor and bend your hips and knees 90 degrees . Contract your abs and raise your hips off the floor, "popping" them into the air as high as you can while you try to crunch your knees to your chest . Reverse the motion to return to the starting position. That's one rep.
