I think it's well worth the investment.
I've got a Gym membership, but to be honest the exercises on here are far different from what I typically do at the gym. The Yoga and Strength exercises are no joke. They will hopefully help me in an area that I rarely have time to work on at the gym (flexibility).
The charts they use for Underweight/Average/Overweight/Obese are a bit off since the game can't calculate muscle mass. If you're just an average body type it would be a bit more accurate.
As corny as it seems I kind of enjoyed the Short Run exercise, and I hate running with a passion. The ski jump is really fun too.
The thing I liked the most is that it got my g/f's parents off their asses. My g/f's dad is a heart attack survivor, and doesn't exercise at all. He put in a good 30 minutes yesterday, hopefully there's enough different activities to keep him occupied.
