OK, so I read on here somewhere that being sore the day after lifting weights is not the sign of a good workout. Ok, so I did weights, and I'm pretty sore today, so what's that a sign of? Over doing it? Should I do less reps? The reason I was reluctant to try weights is because I don't know when to stop. If I just do, say 10 or 20 reps, I don't feel like I'm doing anything. I'm not even tired, and I don't fel like I put any effort into it. So I did like 50 reps on each machine. Back extenders, leg curls, arm things. (LOL.. I have no idea what you call these machines, and no one was there on a Sunday to show me the proper way.) All in all, I went from machine to machine (what are these things called?)... and did different sorts of weights for 30 min. I'm pretty sore today, so now what? Wait till it goes away before I try again? Then do less? This is why I prefer swimming and Pilates.. I can't figure this stuff out.
