FitHRight™ is a solution that combines bluetooth wearable devices, display screens and a mobile app to facilitate group training. Coaches and students can observe heart-rate changes in real-time on the big screen to gauge exercise intensity, provide suitable guidance and motivation. Three display modes are provided for instant flexibility. Gray, blue, green, orange and red colors are used to indicate intensity based on the intensity levels set by the American Medical Association, clearly marking different heart-rate ranges. Data is kept for long-term tracking and personalized workout reports can be managed through cloud services.
