Swimming

Swimming or diving are some of the healthiest exercises you can do.  I've never done it competitively; but I'm pretty good at it, and it WILL make you look hot.
I didn't get hot until college either. That's when people mistakenly thought I was a swimmer, although even in high school people knew better than to pick a fight with me. Nobody ever did that, because I had that vibe of "you give me a swirly, I'll fucking stab you." That worked out pretty good for me.
And I actually am a pretty strong swimmer and diver. Kinda runs in the fam, although I don't really practice that much. There is no pool near my house; but in college, I could outdive pretty much anyone at my co-op. Because in high school, I was actually pretty much forced to swim and dive everyday by my father and my stepmother whenever we lived in a place that had a pool, and in college, I actually was the pool maintenance guy at the co-op. My mother was also a swimmer.
My mother was actually a competitive swimmer, and she actually had a reputation for her swimming. I actually dove into the pool at my co-op for some trinket some girl had dropped there in the cold of winter. I brought it up from the deep end. I don't remember much about it, except that the water was fucking freezing, and I got it back from the icy depths where no one else dared dive.
Also, when you keep the pool clean, you can go skinny dipping with hot chicks.  Fuckyeah!!!
I mean, when I first moved into that co-op that pool was disgusting.  I had to look for the pool supplies and clean it religiously.  Then we drained it, and some skateboarders demolished the plaster, so we had to fix it with epoxy and with epoxy paint.  They did a little mural on it, and they were trying to do more; but eventually, I was like "It's fucking summer, let's just fill in the pool."  Yeah, I'm the one that did that.  It was like 4 am, and I never confessed back then; but yeah, I filled the goddamned pool, and if Rob Schwaggert has a prob with it, he can come and fight me.  Fucking crankhead.
