The computer can be an effective weight-loss and fitness tool. No, you're not going to get fit simply by reading blogs or typing emails to your friends, but you can use it to get started on an effective fitness program. Actually, you probably already know that, which is why you're here!

Online fitness training is less expensive than personal training at a gym, but it has its disadvantages too. For one, there's no one present when you're working out to critique your form. There's also no training appointment that you need to leave your house for, and for myself at least, I know it would be hard to find motivation if I could stay at home. But if you want to work out at home, or you want guidance on your own schedule, online training might be for you. eDiets has a guide to online training that will help you decide if it will suit your lifestyle.
