Aerobics instructors, that is.
I just joined a new gym in our area (LA Fitness). Well, it's new to our area, anyway! And I started out by attending the Body Works class. This is a class that uses weights throughout the session to tone various muscles. The instructors are trained by evil, evil people. So, when instructed to use a heavy weight, you should really reach for the medium weight, for example. At one point in the workout, I had to drop my little 2.5 lb weight because my shoulder muscles were screaming for mercy.
The next day, I took a Step class with abs. It's been at least 10 years since I've done one of the these classes, and fortunately, not a whole lot has changed. But there were moments when I literally laughed as I watched the entire class do some combination off of Broadway while I looked on as a spectator rather than participant.
Today? There's not one single task I can do without hurting. Peeing, petting the cat, blinking...it all hurts. Strangely, eating is no problem :)
