You can snag an Echelon Reflect smart fitness mirror for 60% off. At 40 inches, this model is small enough to work in pretty much any space, and like most fitness mirrors, the design is unobtrusive enough to blend in when you're not using it. This Prime Day deal includes a free trial membership to Echelon Premier, which you need to keep in order to enjoy the mirror; the membership offers live and on-demand fitness classes in strength training, high-intensity interval training, yoga and more.
