When I started training, I was about 95lbs overweight. Since then I have lost about 20-25lbs. My advice is to take it slow, it's very easy to hurt yourself trying to push it too hard. now I still have a way to go, but another bit of advice....don't ever quit because you are overweight. It seems alot of people here are dealing with the same issue and the only way to get rid of it is to keep going, we are all behind you Also, the stretching does get easier as you lose weight. 4-5 years ago, I weighed 205, (mostly muscle, I worked out alot) and could jump kick a target 7-8 feet high and I am only 5'11 and now that I am losing the weight, it is getting alot easier(still cant hit that 8 foot mark, but I will get it eventually) so will you
