I'm 24, 5'10, and range from 150-160 (after some MMA training sessions, I get real low in the 150s). I started lifting when I was 16, about 85-95 pounds primarily as a way to start sizing up as a small person. I've been my own personal "Will this work" training regimen, and have tried tons of exercises and what not.
Some of my personal bests are 245 x3 on flat bench, 100 lb dumbells x5 reps for flat bench, 245 on deadlifts, and about 235 on squats (The deadlifts and squats, are all based on 6 reps or more...never tested myself hard on those and I eventually hurt myself on deadlifts).
Only recently with the addition of MMA training to supplement my weight lifting have I found a positive balance and have I seen some incredible results.
