<human>: Can you provide a brief overview of the text?

Alright guys. After a couple of weeks lurking around this subreddit I've decided that all of your awesome progress makes me feel lazy as all hell. 

Right now I'm a sophomore in college and weigh roughly 149lbs. I'm only about 5'4", however my body proportions don't really let on to my actual weight. I'm perfectly happy with how my body looks, I just know that I'm not in shape. 

In high school I was very athletic, I'm a black belt in Taekwondo, but after a knee injury I pretty much stopped and started to focus more on academics. 

Needless to say I was way more active in high school than I am right now. I've decided to start going to the gym and do a mile on the elliptical five days a week, because running puts too much stress on my knee right now. Definitely starting out slow so I don't make my body angry with me, but after a couple of weeks hopefully I'll be able to do more than a mile. I'm looking forward to being in-shape again.
<bot>: Thanks for making me realize I'm out of shape and giving the motivation to do something about it. You guys are awesome. Keep up the excellent work! :)
