Hyperextension On A Exercise Ball

  • Intermediate
  • Compound
  • Rep-based
  • Back
  • Waist

This exercise targets the lower back, glutes, and hamstrings while challenging core stability due to the unstable surface of the ball. It is highly effective for improving posture and posterior chain strength by forcing the stabilizer muscles to engage throughout the hinge movement.

Muscles worked

Primary

  • Erector spinae
  • Glutes
  • Hamstrings

Secondary

  • Abs
  • Obliques

Equipment

  • Stability ball

Setup

  1. Place the stability ball on the floor and position your pelvis and lower abdomen firmly on top of it.
  2. Anchor your feet against a wall or under a heavy object like a weight rack for stability.
  3. Straighten your legs and keep your feet hip-width apart with toes tucked.
  4. Cross your arms over your chest or place your hands lightly behind your ears.

How to do it

  1. Inhale as you slowly hinge at the hips, lowering your torso over the curve of the ball until you feel a stretch in your hamstrings.
  2. Exhale as you engage your glutes and lower back to lift your torso until your body forms a straight line from head to heels.
  3. Pause for one second at the top of the movement to maximize muscle contraction.
  4. Lower your torso back down with control, following a 2-second eccentric tempo.

Form checklist

  • Keep your neck neutral by tucking your chin slightly and looking at the floor.
  • Avoid hyperextending or 'arching' the lower back past a straight line at the top.
  • Keep your legs fully extended and your feet pressed firmly into the floor or wall.
  • Ensure the movement comes from the hips and lower back, not by swinging the upper body.

Pro tips

  • Focus on pushing your hips into the ball as you rise to maximize glute and hamstring recruitment.
  • Imagine 'peeling' your spine off the ball one vertebra at a time to increase the mind-muscle connection with the erector spinae.

Make it harder

  • Hold a weight plate or dumbbell against your chest to increase resistance.
  • Extend your arms straight overhead in a 'Y' position to increase the lever length and core demand.
