Instructions:

1. Start by standing with your feet shoulder-width apart, holding a barbell across your upper back.
2. Lower your body into a squat position by bending your knees and pushing your hips back.
3. Once you reach the bottom of the squat, explode upwards by jumping off the ground.
4. As you jump, extend your hips, knees, and ankles, pushing through your toes.
5. Land softly back into the squat position and immediately repeat the movement for the desired number of repetitions.
