45° hyperextension bench: how to use it

Muscles worked

Setup

1. Set the pad so it sits at your hip crease, not on your stomach or mid-thigh, so you can bend at the hips.
2. Adjust the foot rollers so your heels are firmly supported and your body feels stable without sliding.
3. Cross your arms on your chest to start; you can hold a weight against your torso later once you control the movement well.
4. Place your feet about hip-width apart, firmly on the platform or against the rollers.
5. Test a few reps with no extra weight to check that the range of motion feels comfortable for your lower back.

How to do it

1. Climb onto the bench, lock your feet in, and rest the front of your hips on the pad, body in line with the bench.
2. Start from a straight position, body in line with your legs, then squeeze your glutes and keep your lower back steady.
3. Inhale and slowly lower your torso toward the floor by bending at the hips, until you feel a stretch in the back of your thighs, without rounding your back too much.
4. Pause briefly at the bottom and stay in control, no bouncing.
5. Exhale as you raise your torso back up until you’re in line with your legs again; avoid going higher than that to keep pressure off your lower back.
6. Hold the top position for a second by tightening your glutes and the back of your thighs, then move into the next rep under control (about 2 to 3 seconds on the way down).

Common mistakes

• Going too high and over-arching the lower back

  Instead : Stop when your body is in line with your legs. Focus on pushing with your glutes instead of trying to lift your chest as high as possible.

• Bending through the back instead of at the hips

  Instead : Think about keeping your back almost fixed and sending your hips back as you lower. Adjust the pad so it sits at your hips, not your stomach.

• Moving too fast and bouncing at the bottom

  Instead : Take 2 to 3 seconds to go down and add a short pause at the bottom. If you lose control, cut the range of motion and remove any extra weight.

• Starting right away with extra weight

  Instead : First master the movement with just bodyweight. Once that feels stable and easy for full sets, then add a small plate on your chest while keeping the same technique.

Coach tips

• Keep your gaze on the floor a bit in front of you so your neck stays in line with your back.
• If you only feel your lower back, push harder through your heels and focus on squeezing your glutes at the top of each rep.
• Start with shorter sets to learn the pattern, then slowly increase your reps or the weight you hold against your chest.
• For controlled tempo, aim for 2 to 3 seconds on the way down, a small pause at the bottom, then a slightly faster but smooth lift.

Variations

• 45° side bend: turn sideways on the pad and raise and lower your torso to work the side of your trunk.
• Back extension with added weight: hold a fixed-weight barbell or a plate on your chest to increase difficulty, keeping the same controlled range of motion.
