hey guys, i was wondering if you could help me out with a problem. i have been taking muai thai for the past four months, but every class my calves tense up to the point where they are rock hard during the warm ups... and i pretty much cant do jack shit. I was told drink more water- tried that. get them massaged- tried that too and while i have noticed improvement, i still have that happen to me and its very frustrating. I dont know what to do and its hampering my workouts. any thoughts would be greatly appreciated.
