Vitness Rx is a solid system. The workouts take less time than it would take me to drive to the gym and suit up, and even though I generally hate exercising, I found them fun to do. But the app could use more features to help me stay motivated between workouts and remember what I'm doing during them.
The user manual suggests alternate workouts—swimming or cycling on Grounding days, walking or "mellow yoga" for Cooling, and interval training or sprinting for Heating, for example—but those aren't mentioned in the app. It's iOS-only too, no Android version. And it isn't optimized for the taller screens on the iPhone 5 and fifth-gen iPod touch.
Still, what's on offer here is generally pretty great. If you're looking for effective workouts that don't require special equipment (or even shoes), and a program that respects the fact that you're not at your best every single day, Vitness Rx is worth a look.
