Kids are fantastic motivators. I have 3 step-grandkids staying overnight & although I didn't feel like it, they really wanted me to join them with Wii Just Dance 3 so we danced. Well, we played for 2 hours straight!! Whew! My routine with the Wii Dance games is that we each take turns choosing a song (youngest to oldest - this includes me of course). Also, we're only allowed to drink ice water & each can drink water as needed - they're special cups on the kitchen counter so they don't spill it in family room. I haven't done this with them in a couple months. I forgot how much fun it is. Kids are delighted, extra exercise for me & I'm feeling great!
