I was very skeptical that this would provide an actual work out. Glad to say that this game is very much made to provide a good workout, provided that you give your best effort. You are able to set your preferred work out intensity as well as the exercises as they unlock for you.
The exercises are simple, effective, and lots of fun to complete while going through adventure mode. Lots of minigames as well.
Overall, very impressed. My 4 year old was also able to use her own profile and is already level 10! She loves it. Great way for a family to have some fun while exercising. I hope some multiplayer features come in the future. Right now you have to take turns between all those participating but still fun to watch and encourage each other.
Looking forward to future dlcs and expansions should they come.
