Ruck
— Made for watchOS and iOS
Rucking is a form of exercise that involves intentionally carrying heavy weight over a distance. It varies from walking, running, and hiking. Burn rates are calculated using formulae such as those from K B Pandolf et. al; factoring in bodyweight, load, terrain, speed, and more. Now you can track rucks in real-time, right on your wrist.
