I used to train at 24 Hour Fitness all the time. Now I say f*ck it. I only train at home now. I got me an Iron Gym and a set of moderately heavy dumbbells and that's all I need to do my full body workout routines. I don't have to pay a monthly fee, I don't have to deal with crowded gyms or difficult people, I can blast whatever music I want. I can grunt as much I want. I can sweat as much as I want, and food and a shower is just a few steps away.
However, I do miss training a lot heavier and certain machines, so I'll probably start going back to 24 this winter or next spring.
