While recently visiting my peeps in Miami, I attended a cycling class at a popular boutique indoor cycling studio. I'm extremely picky about instructors and workouts, but I'm training for my next triathlon and rather than skip my workout completely I prepared myself to do my own thing if I needed to because of whatever foolishness I would encounter in the class. I was hoping to be pleasantly surprised that the class would follow safetly guidelines and that the drills would be effective, but that is not exactly how it went.
Yoga studios tend to have a certain look. Part of this has to do with the practical needs of doing yoga. For example, a carpeted floor tends to hold more dust, and is less desireable for a practice where your face is regularly close to the floor. Part has to do with the rather long and highly fluid history of the practice of yoga.
