Hey Red...That's a good question. I'm doing weight training with a personal trainer for the purposes of negating the muscle mass loss typically related to HT. (Mostly covered by my extended benefit plan)
So far, I think I am maintaining my strength pretty well. Certainly I do get a "feel good" out of it, but I have put on 5 of the wrong kinda pounds, and I'm using the hole in my belt that is 2 positions further away from where it was was 49 days ago. (I did quit smoking at the same time....maybe that's why I'm putting on poundage!)
As an FYI, I am doing "super sets" which is 3 sets of 2 different excercises.
For an example, I do 3 x 15 curls and 3 x 15 rows intermixed with 1 minute recovery periods between each.
So, I would do 15 curls, wait one minute, the 15 rows, wait one minute, then 15 curls...back and forth until the 3 x 15 of each was done.
Then I move on to another dual excercise combo like leg press and chest press, and do the same thing.
Apparently, that's how Arnie did it...
