i've reached my natural limit, but i still like to hit each bodypart once a week (and don't see how you can do it effectively in less than 3 days per week.)
Mon: back & shoulders
Wed: legs
Fri: chest & arms
How do you know you've reached your "natural limit"?
Sometimes you'd be amazed at what you can do, with a few changes here and there. I used to think that I reached that at age 24, when my max bodyweight was 247 lb. I had a max bench of 375 and 17
3/4" arms. This was back in 1997.
I stalled for an number of years. The older I got, the greater I was, in my mind. But in 2004 and 2005, I pushed myself, made some changes in my diet here, went a little old-school there.
By Sept. 2005, I exceeded all my previous limit, DRUG-FREE. I bulked up to 252 lbs., pushed 405 for the first time, and had arms at 18
1/4" arms.
I didn't think I'd be bigger and stronger at 32 than at 24. But, I managed to pull it off.
