Pre-Workout Hydration Tips

Use these tips for optimal pre-exercise hydration preparation.

Drink 2-3 hours before: Early pre-exercise hydration allows full absorption and urination
Top-up 15-20 min before: A small drink right before exercise maintains hydration status
Start well-hydrated: Begin exercise with optimal body water status
Climate adjustment critical: Hot weather requires more pre-workout fluid intake
Include electrolytes: Add sodium to pre-exercise drink for better retention
Avoid caffeine beforehand: Coffee can increase fluid losses during exercise
Monitor urine color: Pale urine indicates optimal pre-exercise hydration
