Never had a problem, but then for fun I beat up sand bags, chunks of wood and have people beat on my arms and legs. (Sand bag conditioning are the only fights I can win--no hitting back!
) Makes sense to me that as with any "art" physical conditioning must be an element of the overall picture.
Tam, why does it have to be the belt? The thigh and the ribs work and I have swoopy sights, even works in the buff.
