Toe Taps

Repeat this exercise for 1 minute. If you feel any lower back pain, don't lower your toes all the way down.

-Toe Taps: Lie on the floor with your arms at your sides. Lift your feet, bending both knees 90 degrees so your thighs are perpendicular to the floor. Now slowly and quietly tap your left toes to the floor, then your right, alternating your feet like this for 1 minute. If you feel any lower back pain, don't lower your toes all the way down. -For a more advanced workout, follow this with 1 minute of side- to- side bicycle crunches, using your hands to support your head.
