Lower Body Power
Primary Muscle Groups – Glutes, Hamstrings, Quadriceps
Secondary Muscle Groups – N/A
Preparation:
The Marine will stand facing the anchor point with feet hip width apart and the TRX at mid-length. They will hold handles with palms facing in and elbows bent at the sides. The Marine will place tension on the TRX by slightly leaning back.
Execution:
The Marine will drop the hips down toward the deck while trying to externally rotate the feet, referred to as “tearing the newspaper”, as they descend. They will keep the chest up and feet flat on the deck. As the Marine descends, the arms will rise upwards while maintaining a bent elbow. Once the Marine gets to the bottom of their squat, they will press into the floor and jump as high as they can. They will give at the hip to absorb the landing force and try to keep ground contact time to a minimum.
Common Mistakes: - Dropping the chest
- Not giving at the hips to absorb the
landing force
