This Is Why You Don't Go to the Gym
I think those theories are missing the main point. Going to the gym is not fun, because gyms have a crappy user experience.<p>So let's say you join a gym, but don't know very much about working out. You walk into a room with hundreds of machines, and are expected to know how to structure a work-out, how each machine works, be familiar with all the muscle groups and exercises, and also really care about planning out and recording every exercise you do to track your progress on the gyms website. It's the biggest turn-off.<p>Why can't a gym hold your hand and treat you like somebody who wants to start working out but doesn't know anything yet? "Express tracks" are a good start, where 10 machines are set up in a row, and if you do 3 sets on each one, you have a good work-out session. That's easy to understand and do. And maybe later, once people have created their habits, they are more likely to learn the finer details. But expecting every new member to care about putting a ton of effort into learning everything about working out is a killer.
