5 moves for strong abs
2. Prisoner get-ups
Lie flat on your back with your hands behind your head. Keep one leg straight and one leg bent with your ankle to the floor. Hinge at the hips as you raise your torso off the floor. While maintaining a tall posture, shift your weight onto your bent knee and raise yourself from a bottom lunge position to a standing position. Lower yourself back to the floor slowly by reversing the steps. Alternate legs each repetition.
Perform 8 to 12 total reps.
Trainer Tip - as you raise your back off the floor, be sure to hinge at the hip. Avoid rounding your low back.
