Caffeine and Exercise: How to Use It to Boost Performance

Caffeine is one of the most researched and effective legal performance enhancers available. A cup of coffee before training can genuinely improve your strength, endurance and focus — for pennies.

How caffeine helps

• Increases alertness and focus
• Reduces perceived effort
• Improves endurance
• Can boost strength and power output
• Enhances motivation to train

How much and when

A moderate dose — roughly 1-3mg per pound of bodyweight (about 1-2 cups of coffee) — taken 30-60 minutes before exercise works well for most people. Start on the lower end to assess your tolerance.

Use it wisely

Avoid caffeine too late in the day, as it can disrupt sleep — which harms recovery more than the caffeine helps performance. Cycling off occasionally also keeps your sensitivity (and the benefit) high.

The takeaway

A moderate dose of caffeine 30-60 minutes pre-workout is a simple, proven way to train harder. Just keep it earlier in the day to protect your sleep.
