Proper Steps:
Begin standing on one leg, with the KB in the same-side hand
Brace your core by pulling your belly button to your spine with your rib-cage tucked
Glide your hips backwards as you kick your heel to the wall behind you
Feel the tension in the back of your standing leg
Pull yourself back up with your standing leg by squeezing where the tension was felt
Rinse. Repeat.
*Make sure KB travels in a straight line vertically, imagine gently sliding it down a tube where your free-leg would stand
