I mentioned the fact that my partner is a soccer player. She was in excellent physical condition when we started dancing together more than a year ago. She has experienced an increase in the muscle mass in her legs, especially in her calves.

I'm almost sixty and was in fairly decent shape when I started dancing with her because I had been dancing off and on for several years. I have also experienced an increase in muscle mass.

To understand how good dancing is for muscle development, compare the legs of a highly experienced dancer to those of, for example, a distance runner or a gymnast. The large muscles of the traditional athlete are overly developed and stand out dramatically. The dancers legs are also very muscular but the large muscles are less noticeable because dancing develops both large and small muscles equally, giving the dancer's legs a smoother and - in the case of the ladies - more pleasing appearance.
