Hello,
I just started weight training for the first time--I've actually tried for a few weeks here and there in the past, but nothing serious. For my arms I am using 15lb dumbells--2 sets of 10 reps--does this sound okay? I am wondering if it's best to lift every other day/on a set schedule, or base it on when my arms stop feeling sore--in other words, should I go ahead and lift even while sore?
Also, if you stop working out, but aren't gaining or losing weight otherwise, will muscle that you gained necessarily atrophy? Just wondering if any of that muscle I gained a few months ago managed to stick around or if I'm starting from scratch.
Looking forward to your input
