We tend to go in spurts and spells on the xbox. We are back on a “lets lose weight for our next vacation” spell right now. So one of the things we have done in the past is pull out the xbox.
Yes they have “weight loss” and “conditioning” games, but I am telling you, Fruit Ninja is the way to go. It gets your blood pumping and your arms working. And it is fun! That is the most important thing. Which means we will do it regularly again. Can’t always say that about the other games 🙂
