I’ve been thinking about this very thing, lately. My wife and I started a weight loss program, which is actually working for me pretty well. However, even though I’m losing weight, my body shape is just kind of “equally shrinking”, instead of getting more…trim. I was thinking that my muscle mass is shrinking faster than my fat mass. I guess I need to get back to the strength training on Apple Fitness (or the free program Fitness Blender).
