Most of us here are not elite athletes, and needn't worry about gaining those few seconds on a climb. Putting on muscle mass is just plain good for your overall health. If you make your living cycling, then sure, you can strive to have that Froome-esque look. The rest of us make a living doing something else, and we cycle as a hobby.
