Setup
- Set a weight bench to a 15-30 degree decline.
- Place a dumbbell upright on the floor at the lower end of the bench.
- Lie prone (face down) on the bench with your knees positioned just past the edge of the padding.
- Secure the dumbbell handle firmly between the arches of your feet, squeezing your feet together to lock it in place.
How to do it
- Exhale and curl the dumbbell toward your glutes in a smooth arc, keeping your hips pressed firmly into the bench.
- Pause and squeeze your hamstrings at the top of the movement for one second.
- Inhale as you lower the weight back down with a controlled 3-4 second tempo.
- Stop just before the weight touches the floor or your legs fully straighten to maintain constant tension.
Form checklist
- Keep your pelvis glued to the bench to prevent lower back arching.
- Maintain a neutral neck by looking straight down at the bench or floor.
- Ensure your feet remain squeezed together to prevent the dumbbell from slipping.
- Avoid using momentum or swinging the weight up.
Pro tips
- Point your toes away from your shins (plantarflexion) to minimize calf involvement and isolate the hamstrings.
- Focus on the mind-muscle connection by imagining you are pulling the bench toward you with your heels.
Make it harder
- Incorporate 1.5 reps by performing a full rep followed by a half rep at the top of the range.
- Slow the eccentric phase to 5 seconds to significantly increase time under tension.
