You're welcome. Hopefully we can save you the years many of us here wasted doing less than optimal lifting.Thanks for the input, Cooter! As I said, I kind of mixed what you guys said with things I read and a little bit from the gym's instructor. I've been working out for a month, but I'll try to lower the number of repetitions while increasing the weight!
I was trying to follow what I was doing previously, but I'll change that. I'll try 3x5! Thanks, Sean!
