Grip a battle rope firmly in each hand and bend slightly at the knees, pushing your hips back so you're in a high squat position. Keep your core braced and a neutral spine. Starting your hands at core level, in an explosive movement bring the ropes upward to your shoulder level as you simultaneously extend the knees and hips to stand tall on the balls of of your feet. At the top of the movement, immediately come down into a squatting position and slam the ropes downward to the ground. Keep repeating this alternating motion while maintaining this high squat position.
