How to Do 45 degrees Back Extension

1
Setup
Position yourself on the 45-degree back extension bench with your hips just above the top of the pad and your feet secured under the foot rollers.
2
Setup
Cross your arms over your chest or place them behind your head, ensuring your body forms a straight line from head to heels at the starting position.
3
Inhale as you slowly hinge at your hips, allowing your torso to descend towards the floor until you feel a stretch in your hamstrings and glutes, keeping your back straight.
4
Exhale as you powerfully contract your glutes and erector spinae to lift your torso back up, stopping when your body forms a straight line from your ankles to your head.
5
Avoid hyperextending your spine past the neutral position at the top of the movement; maintain control throughout the entire range of motion.

Tips

Focus on hinging at your hips, not rounding your lower back, to effectively target the glutes and hamstrings while protecting your spine.
Maintain a neutral spine throughout the entire movement, avoiding excessive arching at the top or rounding at the bottom.
Control the eccentric (lowering) phase for at least 2-3 seconds to maximize muscle activation and improve strength.
Squeeze your glutes forcefully at the top of the movement to ensure full hip extension and enhance posterior chain engagement.

Common Mistakes

×Hyperextending the lower back past a neutral position at the top can strain the lumbar spine; stop when your body forms a straight line.
×Rounding your back during the lowering phase shifts tension away from the glutes and hamstrings to the spinal extensors, increasing injury risk; maintain a rigid, neutral spine.
×Using momentum to swing your torso up reduces muscle engagement; instead, perform the movement slowly and controlled, focusing on muscle contraction.
