I love seeing those scale numbers go down! I haven't (yet) made any changes to my diet or eating habits, this is ALL due to my commitment to my Wii. I do about 20 minutes a day (with a longer 40-50 min session on the weekends) and change it up often with doing my Wii active and other sports games.
I think this is the longest I've kept up with an "active" plan and I definitely look forward to going home and Wii-ing. I was never a gym person and just never found an at-home DVD that kept my interest for long enough. I am so happy to have found my exercise "niche" finally.
I just hooked my Wii to the internet so I can play against my friends who also have Wii's so if you have a Wii and want to connect, let me know!
