Not All Sweat Is Created Equally

Managing electrolyte balance during exercise and competition is vital to optimizing fitness, performance and health. Sodium loss in sweat is not the same for everyone, so take a sweat test to identify exactly what your body needs to stay hydrated. Endurance PTC has partnered with Precision Hydration to offer sweat testing services. Get a customized hydration plan according to your physiology rather than a one-size-fits-all approach.
