Concerns on moving down a weight class
Hey guys, I'm new here and I would like to ask about moving down a weight class. I do Sanshou and my weight is 70kg. So in competitions I would be fighting at the 65kg to 70kg category. However being just 5 feet 6 , I'm smaller than most of the guys in my weight class. Most of them are taller than me and I feel i have to move down to 60-65kg. Any suggestions on how I can lose this weight (I'm quite pudgy) w/o reducing much of my muscle mass and power?
