Should I add weight to back extensions?

Adding weight by holding a plate across your chest can increase resistance once bodyweight becomes too easy. Start with light weight to ensure you maintain proper form throughout the range of motion.

How low should I go on back extensions?

Lower until your torso is roughly perpendicular to the floor or to a point where you can maintain a neutral spine without rounding. Going deeper than your flexibility allows can compromise form and shift stress to the wrong areas.

What is the difference between back extensions and reverse hyperextensions?

Back extensions fix your legs and move your torso, emphasizing the lower back with secondary glute and hamstring involvement. Reverse hyperextensions fix your torso and move your legs, which shifts more emphasis to the glutes and hamstrings while reducing lower back stress.

Back Extension

The back extension is a bodyweight exercise performed on a hyperextension bench that targets the lower back, glutes, and hamstrings by hinging at the hips. It suits lifters looking to strengthen the posterior chain, improve spinal erector endurance, and build foundational strength for compound movements.

Muscle group: Back
Primary muscles: lower back, glutes, hamstrings
Equipment: Bodyweight

How to do the Back Extension

Position yourself on the hyperextension bench with your hips at the edge of the pad and your ankles secured under the footpads.
Cross your arms over your chest or place your hands behind your head, keeping your body in a straight line from head to heels.
Lower your torso in a controlled manner by bending at the hips until your upper body is roughly perpendicular to the floor or as far as comfortable flexibility allows.
Raise your torso back up by contracting your lower back, glutes, and hamstrings until your body returns to a straight line.
Squeeze your lower back and glutes at the top position for a brief moment before beginning the next repetition.

Form tips

Hinge at the hips rather than rounding your spine to keep tension on the target muscles and protect your lower back.
Keep your neck neutral by maintaining your gaze at a fixed point on the floor throughout the movement.
Control the descent and avoid using momentum to swing back up, which ensures continuous muscle engagement.

Common mistakes

Hyperextending at the top by arching the lower back excessively, which can place unnecessary stress on the lumbar spine.
Rounding the spine during the lowering phase, which shifts tension away from the target muscles and increases injury risk.
Descending too quickly or bouncing at the bottom, which reduces time under tension and diminishes the exercise's effectiveness.

Sets and reps

For strength and endurance, perform 3 to 4 sets of 12 to 20 reps, while hypertrophy work typically uses 3 to 4 sets of 10 to 15 reps with a slower tempo or added resistance.
