1. Step-by-Step Sweat Test

To calculate your hourly sweat rate: 1. Weigh yourself in minimal clothing immediately before your workout. 2. Complete 60 minutes of your typical exercise, keeping track of any water consumed. 3. Towel off completely and weigh yourself in the same minimal clothing immediately after. 4. Calculate: (Pre-Weight - Post-Weight) + Fluid Consumed = Total Sweat Loss.

2. Applying Your Results

Use your test results to build a personalized hydration plan, aiming to replace 70% to 80% of your hourly fluid loss during training.
