First time poster here. I am 36, and started taking Kung Fu back in March. Lately I have been questioning my ability to be good in the art. I have arthritic knees, and I have been working towards improving their strength and flexability. In all I go to material class five to six times a week, and conditioning class twice a week. I also lift weights during my lunch hour at work three days a week, and try to hit on the heavy bag at home when I have the time. With all of this, I have been disappointed with my progress. My kicks are not as good as I would like, my balance is less than stellar, and I still have problems getting down into a low stance. I enjoy the time I am in class, and do not have a problem learning the material. I just don't see myself improving as far as the implementation of the material goes. I have wondering if I am expecting alot for ony six months of study, or if I just am not very good at it. Anyone have any opinions they wish to share? Thanks for your time!
