Back extensions: how to do it right

Back extensions lift your torso from a bent position on a dedicated bench. They strengthen your lower back, glutes and hamstrings.

Step by step

  1. Adjust the bench so the edge of the pad sits just below your hips.
  2. Hook your heels and cross your arms over your chest.
  3. Lower your torso by hinging at the hips, back straight.
  4. Rise, squeezing your glutes, until your body is in a straight line, without going past it.

Tip: When it gets easy, hold a plate against your chest to add weight.

Common mistakes

Going too high

Arching above body line loads your lower back. Stop when you're straight.

Pad set too high

If the pad sits on your stomach, you can't hinge at the hips. Lower it to your hips.

Jerky reps

Go up and down slowly, without momentum.
