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!
