  • Hand your subject the yoga block to place between their legs.
  • Place the dowel on their upper trapezius and instruct the participant to hold on to each end in a back squat rack position.
  • Instruct the subject to maintain symmetrical posture while squeezing the yoga block with hips and then rotate left to end-range of motion as well as rotate right to end-range of motion.
