Weigh in before and after a single, shorter session and Electrolytics converts the difference into real sweat volume and estimated sodium, potassium, and magnesium loss.
Before you start: for best results, use the same scale, no clothes, skip food or a bathroom break between weigh-ins, and dry off before your second weigh-in — that's what keeps the number honest. Keep the test window under 45 minutes.
Warning: Consult a medical professional before self-testing. Never perform a sweat test alone, while dehydrated, or in extreme heat. Keep fluids nearby and stop immediately if you feel thirsty, dizzy, faint, confused, unwell, or develop cramps. This test is intended to measure a normal training session—not to encourage delaying or restricting fluid intake. If symptoms are severe, worsen, or do not improve after stopping and rehydrating, seek immediate medical attention. Your health and safety always come first.

Any electrolyte product used before or during this session?
Educational estimate only, not a medical diagnosis. Electrolyte concentration is a population-average estimate by sweat-salt tier, not a lab-measured value — individual sweat composition varies. Assumes no food, fluid, or bathroom use between weigh-ins.
