How to do it

  1. Stand over the loaded stone trainer with the feet a little wider than the base and hinge down to grip its handle or wrap the arms around it.
  2. Pull it into the chest and lap it: sit back and roll it onto the thighs, sitting deep so the thighs make a shelf.
  3. Reposition the hands around it, hugging it tight.
  4. Drive the hips forward and stand up hard, letting it roll up the chest.
  5. Extend fully and place it on the platform or over the bar.
  6. Step back and reset before the next repetition.
