Weight however... no.... not good. Every pound of weight I lose will be four pounds less pressure on my poor knee, which will make it easier for me to move around the mat. Working on it....
Very true. I am rather young, yet a little overweight (for a Marine, anyway), but am highly physical active and maintain a reasonably high level of fitness given Marine Corps standards. That being said, the little bit of excess fat I have from my indulgences has really made a difference on my knees and, to a lesser extent, my lower back. When I was 8-10% BF, going out for a 7 mile run was not problem....now that I'm around 20% BF a 7 mile run, or a three day seminar, takes its toll on me. To compare fitness level, when I was 10% BF, I had a lower overall physical fitness and combat fitness test scores than I do now (though I could run a lot faster then).
