1 - Stand with your feet about shoulder-width apart and position a sandbag securely across your upper back and shoulders, similar to a back squat position.
2 - Grip the sandbag firmly on both sides to keep it stable, keeping your chest lifted and core braced.
3 - Initiate the movement by bending at the hips and knees, sitting your hips back and down under control.
4 - Lower until your thighs are at least parallel to the ground, or as low as you can maintain good posture and heel contact.
5 - Drive through your midfoot and heels to stand back up, keeping your knees tracking in line with your toes.
6 - Fully extend your hips and knees at the top without leaning back, then repeat for the desired number of repetitions.
