The Hexoskin Smart Shirt is the most sophisticated fitness tracker there is, and a favorite among elite sports teams like the Brooklyn Nets.
Since it covers your entire torso, there’s an array of built-in tracking capabilities you simply won’t find in a standard tracker that’s stuck to your wrist and can’t tell the difference between a biceps curl and a sip of beer, including fitness level indicators such as VO2 max, resting heart rate, and recovery capacity along with breathing rate and volume, heart rate, heart rate variability—the variation of heart rate upon time and frequency level—and intensity level.
The shirt requires a dongle that you charge every so often between workouts. Once you’ve plugged it into the shirt (the battery can safely sit in your pocket), you’re ready to go. Then, at the end of (or even during) your workout, pull up the accompanying smartphone app to see all your metrics in one place.
