When I first started the wii, I of course didn't have many excercises unlocked, but as I progressed I started unlocking more and more workouts. I started getting overwhelmed with the excercises and didn't know what to focus on.
With the site I was able to focus on the area that I was interested in. Plus, I never knew they sold wrist and ankle weights until I saw them on the site. After I bought them I was sooooo sore!
Anyway, I just thought I would share. Thanks and good luck everyone!
