Unfortunately...alot of those guys may have a life outside of physical training. I found it quite easy to bulk up and commit to a boxing/grappling program while in college. Once I got a 40 hour a week job...I ended up slimming down. U probably need to find more challenging opponents to push you. I don't see your fighting ability approving unless u find sum1 dat is your size or bigger to push u. U may want to relocate to a gym that has quality sparring partners.
