Hi everyone, New member, long time follower. Just a bit of background: I've been doing kickboxing since October, 3 years of wing chun, and I used to train with some mma guys down the gym when I was 16( nothing serious). I am 6'3 and 139 pounds. My main concern is that there will be such a huge difference in height/stockiness between me and the majority of people in my weight class. Would it be worth putting on 10 pounds to move up to Welterweight(IKF). So, is it going to be worth bulking up to welterweight or potentially even further. Currently focussing on kickboxing, but planning on eventually moving over to MMA. Looking forward to hearing some advice!
