Best Group Training App for Gym!

I have tried several different Group Heart Rate Monitoring Apps for my Gym and Heart Rate Ninja offers the most value at the lowest price.

This app has numerous challenge and competition features that make working out fun for my clients. It has also increased my retention rates and increased my revenue by 20% within the first year of using Heart Rate Ninja!

I am so glad we found Heart Rate Ninja it truly has changed the dynamic of my gym and helps keep us on top of our competition!

Like the idea

Got this app in hopes to compete against friends. Unfortunately it doesn’t seem to run in the background while I’m also using my interval timer.
It is visually appealing, easy set up and seems easy to use.

Love the calorie burn feature!

Love using the Heart Rate Ninja app. It shows me how many calories I burn in each workout. This helps me push myself until I reach my calorie goal each day… and I love the competition!

Visually Appealing!

This app is hands down the smoothest heart rate monitoring app out there. I love all the colors and they even added some funny workout gifs and real time fitness stats. It’s really entertaining and keeps me focused and helps the time fly by!

Great for Treadmill Workouts!

I use this everyday at home on my treadmill. Some days I focus on “blue zone” workouts which help me reduce stress. Other days I push hard in the “orange zone” to help w my endurance. I use the armband which I find both comfortable and accurate. I am in the best shape of my life, since I started using this hidden gem.
