Home Gym vs. Proper Gym

I am contemplating setting up a home gym of sorts. Not that I feel that going to a proper gym is a hassle. Far from it. It's just that sometimes you don't feel like driving 30 minutes during the weekend to go to the gym. FYI, my gym is 5 minutes away from my office. My office is about 30 minutes away from my home (provided that you drive like a civilised human being. If you drive like a maniac on Ecstasy, then it could just take 15 - 20 minutes).

Plus points of having a home gym:

1. I don't have to pay gym membership anymore. It improves my cashflow.
2. I don't have to deal with other people's sweat.
3. No more parking problems.
4. No more fuming at people who hog the equipments.

Plus points of visiting a proper gym:

1. The environment. When you go into a gym you see people exercising. When you go home, the first thing you'll see is the couch.
2. I like the routine of going to the gym. There have been many times when I plan to workout at home but ended up playing Mafia Wars instead.
3. I like observing people.
4. Did I mention about the environment? Oh, yes I did.

Hmm... maybe I'd still setup the home gym but still go to a proper gym. Heheehhehe.. yeah, maybe I'm just nuts. Anyway, my home gym won't have much. Just an adjustable bench, dumbbells of various weights, stability balls and a pull up bar. That would be sufficient to get a total body workout done. Who knows? If I'm crazy enough I may even get a barbell.
