Actually, I've heard many-a-monk describe meditation as training the mind, so the goal is often to 'get a better brain'. Not to mention, an improvement in the brain's mindset is necessarily linked to physical changes in the brain. Furthermore, a sexy body is often chosen to be sexy because the body is healthy and happy in the first place. These motivations are not superficial in my opinion, but rather natural to the human condition.

Exploring the physical and mental benefits of these practices gives a context for practicing meditation in the first place. It takes many years of meditation to be able to consistently let go of 'selfish' desires (emphasis on the ambiguity of selfishness). Entering a practice without a well-defined reason for doing so makes motivation hard to come by. For most folks, the deeper benefits of meditation are only understandable after much dedication.

Anyway, I believe meditation is a means to more than one end. ;)
