Lower Back Curl

What it is

This bodyweight exercise strengthens the muscles along your spine. You lie on your stomach and gently lift your chest from the ground, focusing on controlled movement. This primarily works your spinal extensors, building strength and stability in your lower back.

Technique tips

• Lead the lift with your chest, not your head.
• Keep your gaze down, maintaining a neutral neck.
• Actively squeeze your lower back muscles to initiate the lift.
• Do not press into the ground with your hands or arms.
• Control both the lifting and lowering phases of the movement.
• Focus on slow and deliberate repetitions.

How to track your progress

Log the hold time of each set. Straddly keeps your best hold for this exercise and tells you when you beat it, so a two-second gain does not go unnoticed.
