"I don't believe in the "unliftable body" trick" -DiNalt
Why not? I am a relatively small person -weighing only 90 pounds. Everyone else in my dojo is at least twice my weight, yet if I use weight underside, they cannot lift me up. My brother can't lift me up, and I know he (at least) would not lie. Although, I have to admit I don't think I could keep weight underisde while doing a kick- besides, is a kick even aiki?
