Limit and heart rate lower limit. When the physiological sensing unit 10 detects that the heart rate of the user is higher than the upper limit of the heart rate, the user is warned to reduce the exercise intensity, and when the physiological sensing unit 10 detects that the heart rate of the user is lower than the heart rate The lower limit value will remind the user to increase the exercise intensity, and in this way, the user's heart rate is controlled within a corresponding range at each stage. The flywheel motion mode is used as an example, but this should not limit the scope of patent claims. At the beginning of the training, the user first maintains the warm-up phase with a maximum heart rate of 60-70% for three minutes, then adjusts the flywheel and allows the heart rate to reach a maximum heart rate of 70-80% for 20 minutes, followed by a 2 minute sprint. In the stage, let the heart rate reach the maximum heart rate of 85-95%, and finally the relaxation phase for 5 minutes, let the heart rate drop to 60-70% of the maximum heart rate, and continue to step on when the time is coming, but try to make the heartbeat slow down. In the implementation example of the flywheel mode, the user completes the training according to the range of heart rate set in each stage of the training mode, that is, completes a complete training process. This step-by-step training method can effectively improve the user's physical fitness, and avoid sports injuries or sudden load that causes the heart of the messenger to be too large. In addition, in the same training mode, the user is also provided to adjust the training intensity. The user can understand the physical fitness and cardiopulmonary function status by monitoring the heart rate, and adjust the stronger or weaker training intensity when adjusting to different training. Intensity, the range of heart rate set in each stage of the training mode can be changed accordingly. The physiological signal sensing unit 10 is not connected to the monitoring device 30, and instantly records user usage data, including heart rate data, maximum heart rate percentage, selected training mode, selected training intensity, training time length, and the like. When the physiological signal sensing unit 10 is connected to the monitoring device 30 again, it transmits the usage data recorded by the memory component 14 to the monitoring device, and the monitoring manager can still grasp the user according to the usage data in the offline state. Personal training progress outside of group training.
