Thanks Jennifer and hello all.
I've been researching and reading as much as possible, taking spin classes and I have a pretty good idea how my body is suppose to be/sit/feel on a road bike but no exp. with a spin bike.
To my surprise, out of all the instructors I had classes with, only a hand full actually road their bike and had my attention the entire class. The bad ones, either hovered over their bike in a standing position and gave instructions or pedaled like a turtle "on drugs" for the duration of the class. Early on, I had my bike set up wrong, yet, they (the bad ones) never said a word or corrected me on my form or technique. Later, corrected by a master trainer at a different club on my bike setup, I was APPALLED that some clubs would keep bad instructor on their payroll. GUESS WHAT? I realized, hiring them as "independent contractors", the HC saves major $$$, but their members get the short end of the stick. I didn't like what I saw (point's you've mentioned) and other member's I spoke too felt the same way about bad instructors. The group fitness coord was the worst of the bunch, yet, she gets a weekly paycheck and does the hiring and firing.
The problem, anyone with a credit card will be certified thru MDA simply by submitting a payment of $300.++++ and attending a 8-9hr workshop.
