Back Extension
Lower back, Glutes


Back / Beginner / Isometric (hold)
A prone hold lifting arms and legs off the floor that trains the spinal erectors and glutes.
Why it hurts: Maximal arching compresses the lumbar spine and the neck.
✓ Instead: Lift a few centimetres, look at the floor and reach long rather than high.
