What's the best approach to rehydrate after an intense workout?

April 5, 2026

Quick Answer

After an intense workout, rehydrate by consuming 17-20 ounces of water within 30 minutes of exercise, followed by 7-10 ounces every 10-15 minutes until rehydrated.

Immediate Rehydration

Rehydrating after an intense workout is crucial to replenish lost fluids and electrolytes. Drink 17-20 ounces of water within 30 minutes of exercise to replace the lost fluid volume. This can be achieved by consuming a sports drink or water in 4-6 ounces increments every 5-10 minutes.

Ongoing Rehydration

Continue rehydrating by consuming 7-10 ounces every 10-15 minutes for the next 1-2 hours. This will help to replenish lost electrolytes, particularly sodium and potassium. Aim to consume a mix of water and sports drink to optimize rehydration and electrolyte replenishment.

Monitoring Rehydration

Monitor your urine output to gauge rehydration levels. If your urine is pale yellow or clear, you’re likely rehydrated. Dark yellow or amber-colored urine indicates inadequate hydration. Additionally, pay attention to signs of dehydration, such as headaches, dizziness, and fatigue. If you experience these symptoms, adjust your rehydration strategy accordingly.
