Replenish smarter after every workout.
Athletes know the work doesn’t end when the workout does. Post-exercise recovery is a crucial window for replenishing what’s been lost—especially fluids and electrolytes. To help athletes recover more effectively, the Nix Solo app now includes a Recovery Calculator that delivers personalized post-workout hydration recommendations based on your sweat data.
Using the data collected during your workout, the Recovery Calculator tells you exactly how much fluid and electrolytes to consume in the critical two-hour recovery window. This helps you return to optimal hydration faster—supporting muscle recovery, mental clarity, and next-day performance.
The formula is simple; after a workout, athletes should aim to consume:
These values reflect research-backed guidelines for effective post-exercise rehydration. With the Nix Solo app calculating your losses, you no longer have to guess how to replenish afterwards.
Note: To ensure accurate results, it is imperative that you input the amount you've replenished during the workout before utilizing the Recovery Calculator.
To use the Recovery Calculator in the Nix Solo app, either navigate to Insights and select the given workout from the Workouts tab or if you've just completed a workout and are on the summary screen, simply scroll to the bottom of the summary page.
If an athlete loses 32 oz of fluid and 2,740 mg of electrolytes during a session, the Recovery Calculator will recommend that they consume the following in the two hour post-workout recovery period:
Recovery Calculator Example - Defaulting to All Electrolytes
Recovery Calculator Example - Toggle Between All Electrolyes and Sodium Only. Or select a different beverage option
Hydration isn’t one-size-fits-all. Your recovery needs vary based on your intensity, duration, environment, and personal sweat profile. The Recovery Calculator empowers you to understand and meet those needs with precision—helping you bounce back faster and train stronger.
Whether you’re chasing a PR or simply looking to feel better tomorrow, Nix makes hydration data actionable, personalized, and easy to use—before, during, and after your workouts.
