Which brings up an interesting point. How much of BPing is mental??
Following an accident last year, I was benching 65lbs. Over the following 14/15 months, I've gradually worked up to 175lbs - my goal is 225, about 1.5x my body weight. As I've worked my way up to the 160/170 range, I noticed that this level of weights seriously has begun testing my mental resolve.
About a month ago I was having a seriously bad morning, moodwise, lots of crap going on, and I couldn't push past 3 reps on my first set. Next time around, about 5 days later, I was able to push out my 4x4 without a hitch. The other day, on my first rep of my first set, I realized my grip was uneven as hell, my concentration was beaten down and I got trapped by the damn BB!
In other words, if a puny, skinny guy has the concentration, is it possible for him to lift as much as a bigger guy who can't focus well, all other things being equal?
