The movement, step by step.

  1. Lie on one side and place the forearm under the shoulder.
  2. Stack the legs or bend the knees to reduce the load.
  3. Lift the hips and keep the trunk aligned without rolling forward.
  4. Breathe during the hold, lower with control, then repeat on the other side.

  • Keep the neck comfortable.

Educational guidance, not an individual training prescription. Start with a manageable load, work within a comfortable range, and stop if a movement causes pain. Ask a qualified coach for help with an unfamiliar setup. Practice the technique before increasing load. Repetitions and working weight depend on your goals, experience, and individual needs.
