Secondary Muscles

A back extension exercise performed with barbell loading that develops lower back and glute strength. Effective for posterior chain development and injury prevention.

Instructions

  1. Position yourself in a back extension machine or Roman chair with your torso extended beyond the support pad.
  2. Place a barbell across your upper back and shoulders, holding it securely.
  3. Keep your legs straight and firmly secured under the leg pads.
  4. Engage your core and lower your torso forward at the hips.
  5. Lower until your torso is nearly parallel to the ground or until you feel a stretch in your hamstrings.
  6. Drive through your hips and glutes to extend your torso back to the starting position.
  7. Repeat for the prescribed number of repetitions.

Tips

  • This exercise places significant load on the lower back, so proper form is essential.
  • Keep your spine in a neutral position throughout the movement; avoid excessive rounding.
  • Focus on using your glutes and lower back to drive the movement.
  • Start with minimal weight and progress slowly as strength develops.
  • This is an excellent complement to squats and deadlifts for posterior chain balance.

Recommended starting values

Sensible novice starting points for each goal, for a lifter aged 25–40. Scale down for smaller frames or older lifters. Treat the first set of any session as a discovery set.
