Core: Lift and crunch
Lying on your back, use your ab muscles to lift legs off floor. Extend both hands toward feet and pulsate (think mini-crunches) for 15 seconds. Next, place hands behind head and raise legs to bring feet up toward ceiling. Crunch up and hold, then pulsate for 15 seconds, then lower back down; that’s 1 rep. Do 15 reps.
