OSM (Orthostatic Monitoring) is a method for evaluating your body's response to physical stress through heart rate measurements. This process involves measuring heart rate both at rest and after standing up, allowing for the assessment of adaptation to physical activity. The results are categorized into four zones: Restorative, Pre-recovery, Adaptation, and Stress, providing insights into your body's ability to handle different levels of physical exertion. Whether you're an athlete seeking performance optimization or simply interested in monitoring your health, OSM offers valuable insights into how your body responds to activity.
