Knot Inversion

Make a knot around the height of your mid-back
Separate silks, put them on like a backpack, place hands low on the poles
Sink weight into the silk, placing the knot at the lower back just above your bottom
First step is to try with frog-legs (bend legs and place bottoms of feet together)
Loosen grip and place hands flat on poles at shoulder height
At the same time, lean back, push flat hands into poles, lift frog-legs up to the poles, find balance, and pose in a straddle (this is a knot straddle split position)
To exit, place hands back on the poles, resume frog-legs, lever feet back towards ground while lifting chest up, keeping speed under control
Second step is to try with straight legs
This time, legs together and straight
Straddle legs as you invert and exit, everything else will be the same
