Hey Jane! how r ya? good? alright. well try to explain to your parents how much it means to u to loose weight. if that doesent work, try to save up and by them yourself. ive tried lots of video's and i find the best to be windsor pilates by maury windsor. there great! but very pricy, it cost me 60 bucks for 3 tapes. but lucky for me my sister is trying to loose weigh and she bought them and let me use them! :)lol. so try that, and if u have any questions feel free to post.
