Let’s say you wanted to strengthen several core muscles with one exercise. What would you do? Here’s a suggestion form fitness guru Karen Voight, coming to us via the L.A.Times.
1. Lie face up on a foam roller with your head and
hips supported on the roller. Place your hands on the floor with your
palms down. Start with your knees bent above your hips at a 90-degree
angle. Focus on keeping your abdominal muscles pulled in toward your
spine. Straighten your right leg out in front of you. Pause for two
seconds.
2. Switch legs by bending your right leg and extending your left
leg in front of you. Pause for two seconds, making sure your midsection
stays flat. Continue alternating sides until you have done 30 reps (15
on each leg).
