I've got some kind of mental issue that keeps me from doing heavy weight. Maybe it's not so weird, I don't know.
I think I'll never know what my 1RM max is on bench press, because I can never do heavy weight w/o building up to it. I just don't get it, and it also affects my routine. The lowest I like to plan to go on reps is about 8....which ends up, for example, with me doing....say....8/195#, 8/210#, 8/225#, 8/240#...then as many as i can do at 255#...usually 5 or 6...and then down again at 8 (or fatigue) reps of each until I get back to 210#.
Obviously it's pretty easy going until I get to around 225#, but It just seems like the only way I can feel confident that I'm really lifting as heavy as I can. *Additionally, if you're taking notes, this sometimes puts me doing 6-7+ sets*
So far, no injuries or anything (I've actually gotten around my typical shoulder issues this way), and I am getting stronger. When I first started about 7 months ago, I was doing pretty much the same routine, except I'd start from 150# or 165# and peak at 195#...or maybe 210# if I felt good that day. lol. Also, if it makes any difference, I do this (in addition to flys, etc) on monday and friday, and exclusively on a machine (just further proof of my mental madness).
