It seems like you can do everything on the Internet these days. New web sites are lining up to help you monitor your fitness goals. Considering how expensive it is to hire a personal trainer, an online fitness program might be a better alternative for the cost-conscious. It's hard to beat one-on-one training, but if all you're looking for is someone to help you develop an individualized work out plan and guide you through the stages, you can get that online for much less than in the gym. One example is www.myexerciseplan.com, which will cost you $34.95 for six months.
Good luck with your fitness goals!
