I been trying to do it but I realized that my body weight doesn't go into my punches as it shod so i tried experimenting with gravity and added my own body weight to gravity 65kg as in -65.
I added a replay were I cheek if its possible to keep balance and move at that gravity (turns out it is) but notice that Uke gets decap just by falling down so i think boomshots get to easy this way.
Can you make a good boomshot replay at this gravity (or try your own weight) just for fun? I also gonna try and make one.
