Victoria Song describes the extensive health and fitness data she tracks each day as a wearables reviewer, stressing that her routine is designed to test products and their claims rather than to provide a model for ordinary users. She argues that the pursuit of a highly quantified lifestyle can become excessive, particularly as health technology expands from watches and rings into more intrusive forms of monitoring.

Her current workload is especially intensive because product launch season is starting, she has been cleared to resume training, and she is testing metabolic technology including Twin Health’s “digital twin” system. This involves continuous glucose monitors, blood tests and other sensors, while she also compares new devices against established products such as the Oura Ring and across categories including smart rings, watches and sleep trackers.
