A good pre-workout can be the difference between a flat session and a great one. Here's what's inside, what it does, and how to use it.

What does pre-workout do?

Pre-workout supplements are designed to boost energy, focus, endurance, and blood flow (the pump) so you can train harder and longer.

Key ingredients to look for

• Caffeine — energy and focus
• Citrulline and nitric oxide boosters — bigger pumps and blood flow
• Beta-alanine — muscular endurance
• Electrolytes — hydration and performance

When to take it

Take pre-workout about 20 to 30 minutes before training. Start with a smaller dose to assess your tolerance, especially with caffeine.
