All right, well, I consider it weight training. I'm only doing about fifteen pounds on each arm, which is sadly about all I can handle at this point. Anyway, after a couple days of doing the following...

1) 10 curls
2) 25 pulls
3) 25 bench presses

3 sets of each

...My muscles aren't sore at all. What I'm trying to say is: Why aren't my muscles sore after doing what is difficult for me? Isn't recovery from soreness what makes your muscles stronger?
