One of the best full body exercises; it is efficient and effective.
- Lie on your stomach on a yoga mat. Have your forearms flat on the mat and your toes tucked under.
- Engage your abdominals. Lift your body up so that you are making a 'bridge.' Keep your back straight and your eyes looking down to the floor.
Hold for 10 - 30 seconds, rest, then repeat 2 - 3 times.
