You'll need a 3-foot-long scarf. This move targets your deep abs and six-pack, and also stretches your hamstrings. Do two sets of 8 to 10 pulses per side.
-The Leg Pulse: You'll need a 3-foot long scarf or towel. Lie face up on the floor with your knees bent and the scarf wrapped around your left foot. Hold both ends of the scarf together in your hands. Straighten your left leg. Use the scarf to gently pull your leg close to your head for a hamstring stretch. Next, lift your head and shoulders slightly off the floor, bringing your right leg up to meet the left. -Slowly lower your right leg as far as you can without arching your back. Repeat, pulsing your right leg 8 to 10 times. Then, switch sides. You will complete two sets of 8 to 10 reps on each side. The Leg Pulse works your rectus abdominus, the muscles that give you a six pack, and your transverse abdominus, or your deep abs. Your hamstrings will also get a good stretch.
