- Position your thighs flat on the large pads of the hyperextension bench, ensuring your hips are just above the edge of the pad to allow for a full range of motion.
- Secure your ankles under the foot rollers and cross your arms over your chest or place your hands lightly behind your head.
- Lower your torso slowly by bending at the hips, keeping your spine neutral and back straight, until your upper body is at approximately a 90-degree angle to your legs.
- Engage your lower back and glutes to raise your torso back up until your body forms a straight line from head to heels.
- Pause briefly at the top of the movement, squeezing your glutes, before slowly lowering back down for the next repetition.

Form tips
- Keep your neck in a neutral position by looking down at the floor at the bottom of the movement and forward at the top.
- Focus on initiating the movement from the lower back and glutes rather than using momentum.
- Perform the eccentric lowering phase slower than the concentric raising phase to maximize muscle engagement.
Common mistakes
- Hyperextending or arching the lower back excessively at the top of the movement, which puts dangerous pressure on the lumbar spine.
- Using momentum or jerking the torso upward, which reduces muscle activation and increases injury risk.
- Placing the hip pad too high, which restricts hip flexion and forces the movement to come entirely from spinal bending.
FAQ
How many reps and sets should I perform?
For general lower back strength and muscular endurance, perform 3 sets of 10 to 15 controlled repetitions.
Is this exercise safe if I have lower back pain?
If you have active lower back pain, consult a doctor or physical therapist first. Keep the range of motion small and avoid any hyperextension at the top.
Can I add weight to this exercise?
Yes, once you can easily perform 15 bodyweight repetitions with perfect form, you can hold a weight plate or dumbbell close to your chest to increase resistance.
