<human>: I'm starting a new fitness program today. The main goal is to get myself into better shape, but more important, to get me healthier overall.

When I was in high school I had packed 320 pounds on my 6'2" frame. Once I graduated from high school, all it took was one girl breaking my poor little angsty heart for me to invest in my health. Over the course of 2 years, I lost 140 pounds and was down to 180. I didn't do it by working out almost at all. I simply changed my portion size but not my diet, counted calories, etc. In other words, I got skinny fat. I was 180 pounds but still dreadfully out of shape. It worked for a while. 

Eventually, I fell off the wagon, I started getting older and have put back on about 40 pounds and am up to 225. I am now 26 and the aches and pains of an abused body is starting to kick in far too young. I have to start taking care of myself. I would like to get back down to 180, but the healthy way, instead of the way i did it before: eating garbage, but not a lot of garbage.

I've already put together a decent diet consisting of whole foods, fruits, veggies and lots of chicken. This is good because I love chicken and have a ton of healthy recipes I've managed to scrounge up.

But today, I start the actual working out part. I am starting with the Couch to 5k program that I've heard good things about and my brother who is military and works at a gym is helping me put together a weight program. I'm really excited about this and hope to be a healthy person for it. Except this time, not for some girl or because I don't like being the fat kid. I am doing it because I want the only tool I know I will always have to be in the best working condition possible. I spend countless hours optimizing my computer, tuning up my car and upgrading my electronics, but I spend very little time working on the one machine that I will have to use everyday until the day I die.

Anyway, I'm ranting. Wish me luck.

Can you provide a brief overview of the text?
<bot>: I used to be really fat, then I got thin but was still unhealthy. Put back on some of the weight, getting back on the wagon. Lets do this.
