Pre-Workout

What is pre-workout?

Pre-workout supplements combine stimulants, amino acids, and pumps/focus ingredients (e.g., caffeine, beta-alanine, citrulline) to enhance performance and perception of effort before training.

How does it work?

Caffeine lowers perceived effort and boosts motor unit recruitment. Citrulline can increase nitric oxide and blood flow, while beta-alanine buffers acidity during higher-rep work (effects accrue with daily use). Synergistically, these can raise training quality (more reps, better bar speed) when dosing and timing are appropriate and Sleep and nutrition are solid. Other common ingredients: creatine (helps strength/size chronically, timing flexible), electrolytes for hydration, and tyrosine for focus—none replace sound programming or calories.

Practical application

Start with caffeine at 3 mg/kg to assess tolerance; move up only if needed. Take citrulline 30-60 minutes pre; take beta-alanine daily (timing flexible) to build muscle carnosine. Stay hydrated and include sodium if training hot or long. Avoid high-caffeine doses late day to protect sleep. If sensitive, try lower-stim blends or stim-free (citrulline + electrolytes) and rely on carbs for energy. Skip proprietary blends that hide doses; look for full labels that show clinically supported amounts. If heart rate or anxiety rise, dial back stimulants before adjusting other training variables.

• DoseCaffeine 3-6 mg/kg; citrulline 4-6 g (or 6-8 g malate); beta-alanine 2-3.2 g daily.
• TimingTake 30-60 min pre-lift; beta-alanine timing is flexible but daily consistency matters.
• SafetyTrack total caffeine from all sources; reduce or skip for evening sessions to protect sleep.

Common mistakes

• Mega-dosing stimulants, causing jitters and hurting sleep and recovery.
• Expecting beta-alanine to work immediately; it needs weeks of daily use.
• Using pre-workout to mask poor programming, low carbs, or lack of deloads.
