Don't know if this has been done before, but I've just started playing and found this more or less straight away

DO NOT HOLD ALL

contract both knees

space x1

hold all (c)

contract both pecs
grabby hands

space x 2

extend knees
extend pecs

(p) or add a different ending

(I think I changed my setup by accident, so I apologise if the number of spaces is incorrect)

Its not working.

I might be able to fix though, I have my own, but I like to keep my moves secret ;)
