Grateful for this App

I’ve been a personal trainer for the last several years but I’ve never liked doing cardio myself even though I know the benefits. I was intrigued by the 20 minute workouts and the wealth of research on the benefits of intervals. I started doing the daily workouts and have been more motivated than ever to stick with the schedule of 5 days on and 2 days off. I love how the workouts are never the same and you can feel the flow from one day to the next. After 6 weeks of doing this I feel like my cardio level, breathing, and sleep are better than they’ve ever been. I love how much better I feel and I was already in great shape. I now recommend Zones Cardio to all of my clients, friends, and family.

Response from developer

I'm so glad you are finding our app so beneficial! It's great that you are motivated to stick to a schedule. The workouts are never the same, and that isn't by accident. It was based on a LOT of research, so each day really does flow from the previous one. It's great to hear that your overall wellness has improved. That's why we wanted to create Zones Cardio - so I'm glad it's working for you!

I feel motivated again

I was a high school and college athlete but am now in my 50s. I have slowed down a lot but I still miss that high from doing a “real” workout but just a run. Zones Cardio keeps me from being bored on the treadmill, makes me feel like I accomplished something with my run, and helps me still feel like an athlete.

I'm so glad that Zones Cardio has helped with your motivation and feeling of accomplishment! It really is amazing how fast 20 minutes goes when you're changing your intensity so frequently. We want you to feel great about yourself, so we're glad we could help you feel like the athlete that you are.
