I agree, Catrin. The 2 classes a week I take are very similar to what you describe. I quit going to the Tuesday class, because of the instructor's "military" demeanor (ha, don't tell my son). Yesterday, I decided to ride my bike to the gym at 5 AM, for the 5:30 AM class. I will only do this on Thursdays, not on Monday, after a weekend of riding. I was not happy when I saw the military style instructor there, subbing. But, the class was a little more cardio oriented, so it wasn't so bad.
Some of the other class members were amazed I rode my bike to the gym. I find so many people see exercise as something you only do at the gym. While this is not true for everyone there, the people who run outside/ride weren't there yesterday, for some reason. I got constant questions about how I was able to ride there!
(7 miles, which is the long way, but the way I drive involves a highway traffic circle that is deadly, though only 3.5 miles)
