A little background, I am about 40, short and slightly (alright, maybe more that slightly) overweight with a job that gives me a lot more stress than exercise. Trying to get back in shape after chasing my career for the last 20 years.
My dojo has a supernice guy that I really want to punch in the face. Or more acurately it was seveal supernice guys that I regularly punch in the face, but one in particular that is a big challenge for me. He is about my age but his profession is welder and body mechanic (read modern day blacksmith) so his body hardening is impressive and my ability to manuever him is very limited, he can block most punches without much effort and his grip strength makes grappling with him generally a losing proposition.
I have had some limited success with using the kata based sparring, he likes to throw straight punches and the crowding pressure seem to help. But I am stuggling to generate power with the the close in forearm strikes etc. Does any of the high impact stuff or anything else you guys have tried help with developing that type of power.
More importanly it is not that I simply want to hit my friend (although I do want to hit him) it is also that I figure I am regularly going to be fighting younger men that are substantially faster than me and so being able to play a closer game that takes avantage of my body weight and breaks up their thinking is likley a good direction to take my personal skills.
