  1. 1Feel your hip flexors lift the knee high on each rep
  2. 2Stay tall and balanced on the standing leg
  3. 3Keep your core engaged to control the motion

Common mistakes

  • Don't hunch forward to meet the knee
  • Avoid rushing and losing your balance
  • Don't let the standing knee cave inward
