TZ NYC App helps its fitness club members track and store their workouts outside the club. Trainers are then able to review all members’ activities so they can help them improve performance, keep their weight under control, and enjoy a healthy and energetic lifestyle.

The app works with all chest and arm-based TZ heart rate sensors to provide accurate and engaging cardio frequency-based effort tracking and monitor individual training sessions. Real-time training monitoring makes workouts competitive and engaging and boosts members’ motivation while building a collaborative environment.

Monitor your workouts

The TZ NYC app provides real-time information on your workout and training session so that you can conveniently adjust your effort to suit your training goals, such as tracking your actual heart rate, HR training zone split, duration, or calories burned.

Record and upload your training to the cloud

The TZ NYC app automatically synchronizes each new training session with your TZ account to provide a complete overview of your progress with daily and weekly reports as well as an accurate and detailed analysis of all your workouts.
