Stand with your feet hip-width apart, holding the dumbbells in front of your thighs with your chest up.
Push your hips back as far as possible to lower the weights, keeping the dumbbells touching your legs and your back flat.
Stop when you feel a deep stretch in your hamstrings, then drive your hips forward to stand back up.
Tips
Initiate the movement by pushing your hips straight back rather than bending at the knees, so the dumbbells travel close to your legs throughout the descent.
Keep your spine in a neutral position from your lower back through your upper back as you hinge, avoiding any rounding or excessive arching.
Lower the dumbbells only as far as you can maintain a neutral spine and a strong hip-hinge position, as individual hamstring flexibility will determine your end point.
Common mistakes
Allowing the lower back to round as the dumbbells descend, losing the neutral spine position established at the start.
Letting the dumbbells drift away from the legs during the descent instead of keeping them in contact with or close to the thighs and shins.
Bending the knees significantly as the weights lower, turning the movement into a squat pattern rather than a hip hinge.
Make Every Set Count.
Plan your workouts, track every session, and see your progress over time.
