I keep hearing things about how you cant spot reduce, or how you won't gain muscle unless you have a calorie surplus. But does strength training have any aesthetic benefit if you're on a diet? Will weight lifting make you look better in any way? Or is it just for health reason (minimizing muscle loss, increasing endurance, etc)?
Second, I heard that doing the same unchallenging exercise over and over is counter-productive. Does that mean the net benefit will actually become negative? Are you better off not exercising than doing the same easy aerobics? I have increased the intensity of my exercise and in a few days I've noticed a significant improvement. So I'm not planning on doing it the wrong way, only to gain additional knowledge on the workings of the body.
