Strengthen your core with this yoga-inspired abdominal exercise. Having a strong center protects your spine and supports arm balances and other yoga poses . . . and makes a swimsuit more flattering (just saying). Be sure to pull your abdomen down toward the mat the entire time. Your head and shoulders stay grounded as well.
If you have any history of back injury or are just starting out, please be sure to modify. This is advanced abdominal work and should be done slowly at first. Start with 3-5 repetitions and work up to 10-12.
