I'm currently in training to try to hit a goal of 300 lbs. and I have been working out with a powerlifting routine, working my core and doing lots of rows to balance out my emphasis on bench. I'm 6'2'' and about 180 lbs and am gaining but very slowly. I was at 275 for solid 5 weeks and recently had a breakthrough and hit 285. I feel its gonna be rough to get these last 15 lbs, I've been lifting since I was 14 and I'm 28 now, so I'm confident in my form, do any of you guys have any tips that could help put me over the edge?
