A bodyweight hamstring isolation movement using gravity and body control to contract the hamstrings without equipment.

Instructions

  1. Lie face down on an exercise mat or floor with your legs extended behind you.
  2. Place your hands either by your sides or under your forehead for stability and comfort.
  3. Engage your hamstrings and curl your heels upward toward your glutes.
  4. The movement should be controlled, focusing on hamstring contraction rather than speed.
  5. Continue curling until your feet are as close to your glutes as you can control.
  6. Pause briefly at the top of the movement, feeling the hamstring contraction.
  7. Lower your feet back down to the starting position with control.
  8. Repeat for the prescribed number of repetitions.

Tips

  • Keep your hips in contact with the mat to isolate the hamstrings.
  • Use a slow, controlled tempo to maximize muscle engagement.
  • This natural movement requires no equipment but builds substantial strength.
  • Progress by performing higher repetitions before advancing to weighted variations.
  • Consistency with bodyweight curls builds a strong foundation for heavier movements.
  • This exercise also improves hamstring flexibility when performed regularly.

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.
