who would have thought i'd ever work out?

so, a fear of apathy led me to the gym last august. now, working out is actually fun. who would have thought expending all this valuable energy on "motionless" machines and lifeless weights could be so much fun? i can't say that i do it for my health per se, or to check out people, or to get a svelte body. it's the adrenaline rush. the pursuit of that boundry where your body says, "no", but your mind says, "YES". is this what people experience? i suppose i'm experiencing it now because exercising is something i've chosen to do rather than something i have to do. choice. truly a great gift from God.
