And while using the gym treadmill you can look outside at people walking around for free.
I used to bike to work at an office building that had a spin class studio on the first floor. I was continually bemused at what fucking idiots those people were, wasting their time driving somewhere in order to waste even more time and money paying to ride a bike, when they could’ve just ridden their bike to wherever they needed to go for free and get their exercise along the way. I don’t care what excuses they use to rationalize it; it makes no damn sense.
