Stretching, bananas-----we've heard it before and it may be good advice. King, you have a circulatory/metabolic problem in the specific muscle area or your diet is trash leading to electrolyte imbalances. You can try a multivitamin mineral supplement and drink more orange juice or animal aid, whatever. It might help, dehydration is hard on muscles. Have you ever noticed the prominent veins on body builders? That is blood flow. We don't need to go that far, do we? Yet, the one exercise that can address the circulatory problem is the bodybuilder's heal raises performed on a block or machine. For good luck, you might also want to balance out this with leg curls and leg extensions. These muscle groups work together and we wouldn't want any to get jealous. Your mitochondria will come awake and salute.
