All my life I've done light weights & high reps, to build endurance or for cardio benefits. Recently I learned that men after 40 (that would be me :-) start losing muscle mass, leading to a drop in testosterone, so I want to add some exercises to "bulk up" my chest and biceps to counteract this.

I know the classic approach is high weight/low reps to build size, but I've never done that. The weight I can figure out, I just add 5 pounds whenever I get to the maximum number of reps. But how many reps are the maximum?

I used to do 3 sets of 15 before increasing the weight when I was working a "low weight/high reps" routine; should I do 3 sets of 8 now? I'm at 8, 7 and 7 on curls today... should I raise the weight after I can do 3 sets of 8, which would get me up to higher weights sooner? Or should I hold it to 3 sets of 10?

Any advice from those who've done this? Thanks!

Got a question for network gurus. We're getting a sporadic problem here in which Web browsers (Firefox/IE both) tell us a site is unavailable, but other apps (IM, Outlook, and ping) can connect to the net just fine. I've tried ipconfig /flushdns, and ipconfig /all shows that we're hitting the ISP's DNS servers. Any ideas on stuff to look at? Any recommended sites/forums for troubleshooting this?
