Help with a decision on weight
So I'm struggling with a decision on the weight best for me to fight at. I'm 5'10 and walk around 138-140. The question is do I go to 125 or bulk up and fight 135. I'm leaning towards 25 but hearing from some it's a bad idea some say I should. Every time I fought at 135 the dude was way bigger, and I fought at 130 once and felt great. They said I'm to young to be able to stay that light for long me being 18. So what do you guys think do I try it once see how it is, go for the size up? Thanks for the feed back
