Setup
- Sit on the edge of a flat bench with your right leg extended straight in front of you, heel on the floor and toes pointed up.
- Bend your left knee and place your left foot flat on the floor for stability.
- Sit tall with a neutral spine, engaging your core and pulling your shoulder blades back and down.
How to do it
- Inhale and reach both arms forward toward your right foot, initiating the movement by hinging at the hips rather than rounding the spine.
- Exhale as you lower your torso toward your thigh, maintaining tension in your lats and upper back to keep the reach active.
- Hold the deep stretch for 2 seconds at the bottom, focusing on pulling your chest toward your knee.
- Inhale as you slowly reverse the hinge to return to the upright starting position, then switch legs after the set.
Form checklist
- Keep the extended leg's knee straight to maximize hamstring tension.
- Avoid excessive rounding of the lower back; focus on the hinge at the hip joint.
- Keep your neck neutral by looking toward your shin rather than straining to look forward.
- Ensure your hips remain square on the bench throughout the movement.
Pro tips
- To maximize lat and trap engagement, reach as far past your foot as possible while keeping your shoulders depressed.
- Flex your quadriceps on the extended leg to trigger reciprocal inhibition, allowing the hamstrings to stretch more deeply.
Make it harder
- Hold a light weight plate or medicine ball in both hands to increase the demand on the posterior chain and upper back.
- Perform the movement with both legs extended simultaneously to increase the intensity of the hamstring stretch.
