Hardcore Upper & Lower Ab Workout

This awesome abs exercise comes from a core focused yoga sequence by Tara Stiles. What's so great about this move is that it works both the upper and lower abs.

1. Lie on your back, tucked into a ball, making sure to glue your lower back to the floor.
2. Extend your legs and arms straight into the air. Round your back as much as possible and reach for your toes.
3. Extend your legs in front of you, and arms straight behind your head. Keep your heels hovering just above the ground and lower back glued to the floor.
4. Come back into a ball and repeat for 12 total reps.
