Step by step

  1. Select the appropriate load and adjust the pad to be over your Achilles tendon (above the heel) when you lie down.
  2. Lie down, grab the handles, and place the back of your lower legs against the pad.
  3. Take a breath and engage your hamstrings to curl your legs, lifting the weight.
  4. Curl until your lower legs are almost vertical and exhale at the top.
  5. Hold for a moment and extend your knees slowly as you inhale.
