Back Extension
Lower back, Glutes


Back / Intermediate / Compound (multi-joint)
A bench exercise for the lower back, with the glutes and hamstrings assisting.
Loads the lower back. Use a load you can control and skip it if it causes pain.
Why it hurts: Hyper-extending the lumbar spine at speed pinches the facet joints.
✓ Instead: Rise until the body forms a straight line and stop there.
Why it hurts: The hips cannot hinge, so all the bending comes from the lower back.
✓ Instead: Set the pad just below the hip crease so you fold at the hips.
