The Eternal Beach-Body Plan
Phase I - Week 1: Workout I
Exercise VIII: Bent-Knee Static Bridge
Sets: 2 Reps: Hold for 90 Seconds Rest: 45 Seconds
Get into pushup position, and then bend your elbows 90 degrees so that your forearms are resting on the floor. Bend your knees as well so that they rest on the floor to support you (raise your feet in the air if you want to make the exercise more challenging). Your body should form a straight line. Hold the position for 90 seconds. That's one set.
