Seriously, how the heck do you figure out if you've put on, say, 5 lbs of muscle vs. just 5 lbs of fat? Every time I step on the scale at the gym and it says I've gained weight, I get all sad about it and pretty much won't eat dinner after as a penalty. But I'm starting to wonder if that's actually "good" weight I'm putting on. How do you know?
