The key to getting shape is not only a good work out, but also a good diet. If you want FAST results try combining an hour of cardio every day along with a protein diet. The most effective one is having egg whites for breakfast, tuna straight out of the can for lunch with no mayo or anything of that sort, and for dinner tuna again. I would highly recommend that you hire a personal trainer just so that you can get on the right workout and so that you can learn the proper way to lift weights. Ask someone that works at your gym to recommend supplements and also ask them where to get them. If i was you I would stay away from places like GNC. There stuff is overpriced and not any better than something you can purchase from a trainer at the gym or some of the online stores. One last thing; be consistent and do not expect results in ONE week. IT TAKES TIME. Cheers
