45 degrees Back Extension
Strengthen your lower back and glutes with the 45-degree back extension. This effective exercise improves posterior chain strength and stability.
Description
A strength training exercise that primarily targets the lower back muscles. The individual leans forward on a 45 degrees bench, then straightens their body to a flat position.
How to Do 45 degrees Back Extension
- 1Setup
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.
- 2Setup
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.
