I just started working out. This winter I wanted to focus on trying to get on mass and gaining weight since I'm 6'1 150. I want to get to 175. I want to do some bjj, kickboxing, or Muay Thai for cardio And laying the smack down. Should I wait until I get to goal weight or do it while I also lift?i actually want to take it more serious to get the full benefits. So maybe even some sparring. Just dont want to wear my body down to quick.
