What Is Pre-Workout — and How to Use It

Pre-workout is designed to help you train with more energy, focus and output. But formulas vary wildly — and so does quality. Here is what pre-workout actually is, which ingredients matter, and how to use it well.

What is pre-workout?

Pre-workout is a supplement you take before training to support energy, focus and performance. Most come as a powder you mix with water 20–30 minutes before your session. The best ones are transparent about what is inside and at what dose — no hidden “proprietary blends.”

The ingredients that matter

• Caffeine — the main driver of energy, alertness and perceived effort.
• Citrulline malate — supports blood flow and “pumps” during training.
• Beta-alanine — associated with performance in higher-rep, fatiguing efforts (the harmless tingles come from here).
• Betaine & electrolytes — support performance and hydration during hard sessions.

What matters is not just the ingredient list, but whether each is included at an effective, disclosed dose.

How much and when to take it

• Timing: 20–30 minutes before training.
• Caffeine: a common effective range is ~150–300 mg — start lower to assess tolerance.
• Avoid late sessions: skip caffeinated pre-workout within ~6 hours of bed so it doesn’t affect sleep.

How to choose a good one

Look for a fully-dosed, fully-transparent label, a caffeine level that matches your tolerance, and a flavour that mixes clean. Avoid formulas that bury tiny doses inside a blend.
