Yes, there are loads of fitness sites out there. Some will let you track weight loss, some will provide a training program for you and some will let you record your workouts.
But my issue is being able to stick with whichever training schedule I have set up. I would like a web site where I can fill in my own types of workouts, plan a week of them, and even plan a season. Then I would like the site to email me and ask me if I've completed a workout, and if not, to ask me why not.
Does anything like this exist?
