Gym Visit

Since I'm a graduate student, I'm already on campus a huge portion of my life and I'm required to pay fees for our Student Recreation Center, which is code for a fancy gym.  You know, pool, indoor track, weights, the works.  So as part of our homework assignment, I stopped by today.  I don't really hate gyms, but can't say I like them either.  There are always people grinding away on some cardio or weight machine and it really seems like 90% of people there have no idea what they're doing.  We've just been trained culturally that if we put in our time, our lives will be better.  Unfortunately, if you don't work out intelligently or with sincerity, this just simply isn't true.  So yeah, a lot of overweight people on exercises bikes, a lot of dudes that look really strong but also pretty damn fat.  The thing that really bothers me most about gyms, though, is that people drive there.  I realize that some people live far away and want to lift, but it's on a damn college campus.  How hard is it to walk the 5-10 minutes to get there?  Why would you drive somewhere just to run on a treadmill when walking there and back would get you the same workout?  And be better for the environment?
