it varies bor.
At 19 I was the eptiome of a college basketball player; lightning quick, lean, 40 inch vertical, and endurance all day. Strong? not really.
At 23 I was an Army infantry officer with limitless endurance. I was less of a sprinter, a little bit less ripped, but one tough mofo who never got tired.
At 26 I was lifting the whole gym. I was 265 pounds, strong as fuck, pretty lean too. Bench, squat, deadlift; there was not enough iron in all of GA for me. Cardio more or less went out the window though.
At 29 I am strong, though not nearly as strong as at my peak. I am 235, lean, and I do lots of cardio.
So I miss my 19 year old body. But things are pretty good now too.
