3. Box (or Bench) Jump
Face a knee-high bench or box, arms raised. Drive your arms down, push your hips back, and lower your body. Push your arms up, jump onto the bench, and land. Step down. Repeat.
4 Barbell Good Morning
Using an overhand grip, hold a barbell across your upper back. With your knees slightly bent and back naturally arched, bend at your hips until your torso is almost parallel to the floor, and raise up.
