How to use
- Record body weight before and after one workout in the same clothing state.
- Enter the session length and how much fluid you drank during the session.
- Use the result to refine a training-day hydration plan after your daily baseline is already known, then move to Dehydration Percent if you want body-weight context first or to Rehydration Plan if you need a post-session replacement schedule.

Move from daily hydration planning to workout-session adjustment
This page sits after Water Intake and Hydration Schedule. It answers one narrower question: how much fluid did this session appear to cost per hour?
How to choose between nearby pages
Use Water Intake when the daily liters are still unknown. Use Hydration Schedule when the daily liters are known and the next job is timing. Use this page after a real training session when you want a session-specific fluid-loss estimate. Once that estimate looks stable, feed it back into the training-day schedule, then move to Dehydration Percent if you want relative body-weight context, to Workout Hydration Plan if the missing step is the drink rhythm during the session, to Sodium Loss Estimator if the next question is the rough sodium range behind that fluid loss, to Electrolyte Needs if the remaining question is plain water versus electrolyte support, or to Rehydration Plan when the next question is how quickly to replace the lost liters.
FAQ
What does this page calculate?
It estimates session fluid loss and an hourly sweat-rate shortcut from pre-workout weight, post-workout weight, session duration, and drinks consumed during the workout.
When should I use this instead of Water Intake or Hydration Schedule?
Use Water Intake when the daily hydration baseline is still unknown. Use Hydration Schedule when the daily liters are already known and you want a timing plan. Use this page when the question is specifically about workout-session fluid loss.
Is this medical advice?
No. It is a simple planning estimate only and does not replace sports medicine or medical guidance.
What is stored in the share URL?
The share URL stores pre-workout weight, post-workout weight, weight unit, session duration, and drinks consumed.
