I love the SP food manager but the workout area is always a little off no matter what web site you go to due to there being soooo many ways to exercise. I bought the Jullian Michaels wii work out game and she kicks my butt all the time and of course they do not have the calories on this site so I use a watch that has a heart monitor and it tells me how many cals I lost. I then put it as a note under the exercise part of the website.
By having a calorie counting watch/monitor thing, you can really get in tune with your normal calorie burning self. My husband bought me one for christmas about 3 years ago to help me get started in managing my weight and its awesome!! Worth the $300 he spent. They are not all that much.
