For my birthday I bought myself a Wii. With it I purchased the Wii Fit, Zumba 1, and Zumba 2.
I will be doing some of it every day and let you know if it is that effective.
If you ever have questions or have something that you would like me to try (as long as it doesn't cost too much) let me know and I will try to work it in. Thanks all!
