Professional athletes need to know more information than how far they walked or how long they exercised for, so the 'Whoop' Smart Trainer is designed to offer enhanced data.
Able to be used by professional athletes to help track workouts, the 'Whoop' works by measuring the usual data like heart rate and motion. It goes the next step by keeping track of your skin conductivity and even the ambient temperature of it. This allows it to get a much more accurate snapshot of how hard you're really working in comparison to the training efforts.
The 'Whoop' Smart Trainer relays information to coaches to allow them to instantly see how athletes are fairing in comparison to the workouts to see if anything should be adjusted.
