How to Perform

Position your mid-back against a stable bench edge, keeping knees bent and feet flat on the floor shoulder-width apart. Center the barbell across the crease of the hips, using a pad for comfort and support.

  1. Brace your core and drive your hips upward by consciously squeezing the glutes.
  2. Lift the hips until your body forms a straight line from shoulders to knees.
  3. Pause briefly at the top, achieving peak glute contraction without hyperextending the lower back.
  4. Slowly lower the hips only two to three inches from the peak.
  5. Immediately reverse the motion, driving back up to maintain constant tension.
  6. Maintain this short range of motion throughout the entire set.

Coaching Tips

Form Cues

  • Squeeze glutes hard.
  • Hips up, ribs down.
  • Short, controlled range.
  • Maintain constant tension.
  • Drive through your heels.

Breathing

Inhale as you slightly lower the weight; exhale forcefully as you drive the weight up and squeeze the glutes. Maintain a strong abdominal brace.

Tempo

2-1-1

Range of Motion

Start just a few inches off the floor or mat at the bottom; finish when the hips are fully extended and the torso is parallel to the floor.

Safety

Safety Notes

  • Ensure the bench is stable and will not slide away from you.
  • Always use padding between the barbell and your pelvis.
  • Control the weight carefully through the entire partial range.

Spotting

Not recommended; use a slow, controlled weight that you can handle safely. If needed, use pins or blocks to secure the barbell.

Common Mistakes

  • Letting the hips drop too low and resting at the bottom.
  • Hyperextending the lower back at the top.
  • Driving the hips up using excessive speed or momentum.
  • Allowing the knees to cave inward.

When to Avoid

  • Acute lower back pain or lumbar disc issues.
  • Severe pain or pinching in the hip joint.

Flexibility Needed

  • Ability to achieve full, pain-free hip extension.

Build Up First

  • Competency in a standard bodyweight or dumbbell glute bridge setup.
