I just got a new apartment, and frankly... I have an extra bedroom. It's just sitting there (I have my desk in the living room), with a spare futon mattress and nothing else. Thusly, I wish to make it useful.
So, I thought of creating a home gym. I've heard the basics are a bench, a bar and some barbells, dumbells perhaps, and some bodyweight exercise tools a la 'zis:
-for pullups, dips, modified pushups, etc. I'd also get a yoga ball because they can be ridiculously useful in creating bodyweight exercises.
So, for the fitness aficionados on these forums, what other basics might you add to a home gym? Also, is there any reason ye prefer being a member of and going to a gym outside of your home?
