Been using it for almost a month now and it’s really cool! I think I have found my favorite way to get good exercise—even when I’m feeling unmotivated!

As an avid runner, I didn’t think I would like this but I was wrong! Love that it allows you to conveniently train at home but it’s more exciting than simply sitting on an exercise bike or rower.
