8. Whoop 4.0: The Next Level Recovery Tool

The Whoop 4.0 takes recovery tracking to the next level. It’s designed to capture your key vital signs—blood oxygen, skin temperature, heart rate, sleep quality, and more—continuously. It’s smaller than its predecessor, the Whoop 3.0, by 33%, but fitted with a more powerful sensor. The Whoop 4.0 has a four- to five-day battery life, Bluetooth capability, and is waterproof up to 10 meters. It’s a subscription-based service, but the in-depth insights it provides into your sleep, training, and recovery make it a worthwhile investment.
