Well, I can give you some kick ass exercise strategies, but most of mine are actually geared towards weight gain, in the form of muscle. I'm not looking to lose weight or get thinner. I'm already naturally too skinny. But I know that cardio is the best for losing weight. Running is excellent, biking might be even better. Get yourself a bicycle and ride it all over the place, you'll lose a decent amount of weight.
If you're interested in gaining a lot of muscle, then PM me, cos I can show you how to get some fuckin' flawless biceps and abs like I have.
