The Priming Calculator uses your Nix profile metrics, upcoming weather forecasts, and historical Nix workout data from similar environmental conditions to create a personalized pre-workout hydration strategy.
By analyzing your sweat profile under conditions comparable to those expected for your next session, the Nix Solo app combines this data with your bodyweight (entered in the profile tab) to generate individualized hydration recommendations.
Based on published literature, athletes are advised to consume 2–4 mL of fluid per pound of bodyweight during the 2–4 hours before training. Building on this guidance—and integrating your unique electrolyte data from past Nix workouts—the Priming Calculator delivers a tailored strategy to help you start your next workout optimally hydrated.

Review the results from the calculator. Based on this athlete's historical workout data, she should aim to consume 9.5 oz of fluid and 697 mg of electrolytes in the two hour period leading up to her outdoor running workout in Tempe.
The priming calculator is available for outdoor workouts only. Additionally, athletes must have logged at least 1 workout type to get results. For example, if you only have running workouts, this calculator will not provide a recommendation when selecting a cycling workout.
