How to do it

Stand holding a very light barbell in front of your thighs. Slowly lower the head and curl through the spine as the bar descends close to the legs; stop at the lowest range you can control without forcing the stretch. Reverse the motion gradually to stand tall. Do not use momentum or heavy loading.

Form cues

  • Use only a very light load.
  • Roll down slowly.
  • Stay within a controlled range.
