IRONPACK

Single-Leg Hamstring Curl

Muscles worked: Hamstrings.

How to do it

  1. Set the machine so the pad sits just above your heel and lie or sit as it dictates.
  2. Strap or settle one leg in and leave the other resting.
  3. Curl the working heel toward your glute, hips pinned down throughout.
  4. Do not let the hip lift to help - if it does, drop the weight.
  5. Lower slowly, then match the reps exactly on the other side.
