Exercise guide

Lying Isometric Hamstring Bridge

  • Beginner
  • Compound
  • Timed hold
  • Hips
  • Lower legs
  • Waist

This isometric hold targets the posterior chain, specifically emphasizing the hamstrings by increasing the knee angle compared to a standard glute bridge. It is highly effective for building tendon resilience and positional strength in the hamstrings and glutes.

Setup

  1. Lie flat on your back on a mat with your arms by your sides for stability.
  2. Extend your legs so your knees are only slightly bent (roughly 30-45 degrees), placing your heels firmly on the floor.
  3. Pull your toes toward your shins (dorsiflexion) so only your heels are in contact with the ground.
  4. Engage your core to flatten your lower back against the mat.

How to do it

  1. Exhale and drive your heels into the floor to lift your hips 2-4 inches off the ground.
  2. Hold this elevated position, maintaining a straight line from your shoulders to your heels.
  3. Maintain a steady breathing pattern (inhale through the nose, exhale through the mouth) while holding the contraction.
  4. Lower your hips back to the floor with control once the hold duration is complete.

Form checklist

  • Keep your hips level; do not let one side sag toward the floor.
  • Ensure your knees do not cave inward during the hold.
  • Avoid over-arching your lower back; keep your ribs tucked and core braced.
  • Maintain the distance between your heels and glutes to keep the tension on the hamstrings.

Pro tips

  • To maximize hamstring recruitment, actively try to 'drag' your heels toward your body without actually moving them.
  • Focus on a posterior pelvic tilt (tucking your tailbone) to ensure the glutes are assisting the hamstrings and protecting the lower back.

Make it harder

  • Walk your heels further away from your body to increase the lever arm and tension.
  • Perform the exercise as a single-leg hold by lifting one leg off the ground while keeping the hips square.
