Oh, gosh, I'm like the exact opposite. I tried working out like twice with my friend. I didn't enjoy it at all.
If I did care about working out, I would definitely be like this. Back when I was a self-described 'fitness freak', I needed to be by myself. I couldn't socialise with other people, I didn't want to. Though, lol, this behaviour was a symptom of a more, uh, destructive issue. But still! If I went to a gym today, I wouldn't be able to go with anyone, I'd just take my iPod and put on 'work playlist' (Twerkin!!!! by Kreayshawn) and go at it, lol.
I've personally been working out since October 2011. I've lost around eighty pounds so far, but I've got a lot more room to improve. I started off by going late at night to avoid people, but now I go during peak hours. I just don't care anymore. :]
And we're all proud of you!!!
I work out because I want to be in better shape and I feel it will make me more attractive/healthy. I know that's not the right reason to work out, but it's worked so far. :c
Work out for whatever reason you want to, lol. Who cares whether it's the 'right' reason or not, if it makes you feel good, then work out for that reason.
To answer the original questions, however:
1. What the hell is a gym? Gym? What's that?
2. Do I exercise at home? Yeah, I go for runs and whatever and try to keep reasonably fit. I could totally lose some weight, but I don't have the vitality of my early teens.
3. My motivation to stay fit is that I don't want to end up like
K-Fed.
