Heh, kinda reminds me of how I completely demolished a hospital bed when I was about 4 years old and had just woken up after surgery.
According to my mom it was due to an extremely low blood-sugar level causing me to rage like no tomorrow, and not even 5 staff members could stop me at that point.
@Kuro: I'm just a poor college student, so a basic gym is doable, but nothing above average or really 'professional'.
Make sure you look for a gym that's relatively unpacked then. Most gyms have at least a couple of PE teachers who can give you hints and/or a hand in selecting the exercises you should be doing; some of them are quite good. Keep an eye out for teachers that look out of shape though, as they tend to not practice what they preach and therefore are unaware of the consequences.
The downside of such teachers, of course, is that you don't get their undivided attention, and therefore you need to really look into what you'll be doing. Above all, when exercising, remember not to overdo it. You need to work as close above your limit as possible but without "killing" yourself. Muscle gain is basically a repetition of a process in which you take slight muscle tissue damage, and once your body recovers, the fibers will be stronger. Losing fat, on the other hand, requires aerobics. You can't do both
at the same time, but you should work in such a manner that you neglect neither.
I work out three times per week, Mondays, Tuesdays and Thursdays. On Mondays and Tuesdays I run; On Tuesdays I work the irons. I've gone from steadily gaining weight to maintaining it and replacing the fat with muscle over the course of nine months or so.
