And we are here for the goals of progressing fitness levels, improving coordination, cultivating rhythm, increasing strength, and endurance. And how about it's all just for fun. That's how I feel, it's all just for fun- it's just fun with benefits such as all the above. If you need a little inspiration to move today, tune in to the show.
