Anyone go from lazy - fitness freak? Share stories here!!

Been there and back a couple times. Guess I'm kinda a cyclical fitness freak.

I go hard... Life happens, *ish comes up. I miss a workout or 10... get lazy... haven't worked out in months, then
I go hard... Life. (I think you see where this is going)

Trying to keep my Fitness Freak status!

Yes I used to be really lazy, I discovered heavy lifting and fell in love.

3 months ago I was heavily obese, always tired, constantly had headaches and would nap just about anytime I could.

I've had one headache in 3 months, have shed nearly 3 stone and have so much more energy! My buzz is the gym and planning my food.

I went from playing video games in all my spare time to hitting the gym for hours on end. I workout 2 to 4 hours a day 4-7 days a week.

Ummm......ME! I love anything fitness that makes me sweat and burn!

Yes. I used to be a total couch potato, hating sports and exercise with a passion, except for the occasional hike. Wanna know what changed? Four years ago, I bought a Czechoslovakian Wolfdog puppy. Since then, my whole personality changed drastically - it's as if I finally found the nerve and courage to become someone I've always wanted to be, but didn't know how. I've always liked dogs, but to this day, I don't really know why I chose to adopt one, of such an extremely difficult breed no less, at that time of my life. All I knew was that I was 19, first year in college, and depressed beyond anything I'd ever experienced. I just needed... something radical.
Ysanne the wolfdog changed my life. I really got into dogs and training, researched everything so that I could care for my new best friend properly, and since many people have trouble raising members of this breed, I was determined not to fail and prove to myself and everyone else that I could do this. Czechoslovakian Wolfdogs need extreme amounts of exercise, and my activity levels soared. I got back into hiking and found a connection with nature I always knew was there, but had almost forgotten about. My hikes started getting longer and more frequent. Then I started feeding my dog raw meat and veggies, and had to learn plenty of stuff about proper nutrition for canines. That made me take a closer look at my own diet, but I ignored it at the time. Two years passed, and although I was still very overweight, I was also a lot more fit. Soon, one dog simply wasn't enough. Now I'm a proud owner of a working line sable German Shepherd as well. He is really hyperactive, and with two large, energetic dogs in the house, I started moving even more. Soon, I added swimming and biking to my lifestyle, all of it just to keep up with the dogs. I refused to be an irresponsible owner and wanted to give them both long, happy, healthy lives. To my horror, one day I realized I had actually started LIKING all the exercise.
It was April 2013 when I truly understood my exercise level were more than above-average. I had a hard time believing this, as I always used to be the fattest, slowest person in every group I found myself in. But that was no longer true. It was as if a halo of understanding suddenly lit around my head - I realized I didn't NEED the excess weight anymore. The kind of person that used the weight as a shield grew up, and was now confident enough to do without. I sat my *kitten* down in front of my computer, and for the first time in my life actually had a look at how much I was supposed to be eating per day.
Here I am, four months later. I've lost 12 kg, that's 25 pounds, and am still going strong. I took up running. I found a new job and will finally take the riding lessons I've always dreamed of. I actually have some muscles, despite still being overweight. The dogs are healthy and happy, and have trouble to keep up with me. They're 4 and 2 now, and I'm 23.
You can do it. It's fun. You only live once - don't waste your chance.

YEP! Right here.

I wouldn't call myself a fitness freak but I'm currently training for a full marathon. 10 months ago I'd be out of breath and sweaty taking the garbage out from my office to the dumpster. I've always hated exercise and anything that involved hard physical work but I've always wanted to run. I started in January only able to do 20-30 seconds at a time, every week slowly increasing my mileage and here I am 2 weeks from race day. My longest run to date was last weekend at 37.2 km. Over the last few months I've discovered I love distance running which is why I switched to a full marathon from the original 10km I planned to do this summer.

Until 2011, zero exercise. First half of 2011, regular exercise but it was just a chore i did for results. Since mid/late-2011, regular exercise and I love it!
