Knot Helicopter Prep

Start on any of the four sides to strengthen (back, front, left side, right side)
Place knot below waist and above hips, at lower back just above bottom
Balance on your back for length of time, then front, then each side
Balancing for 10 seconds and working up to a minute per side will get you stronger for helicopters, stars, and a lot more
