الإجابة باختصار

Take 3 to 6 milligrams of caffeine per kilogram of bodyweight, roughly 45 to 60 minutes before training. Tolerance builds within two to three weeks of daily use, so save it for your hardest sessions. Nothing after mid-afternoon: the half-life is five to six hours.

أسئلة شائعة

How much caffeine should I take before a workout?
3–6mg per kg of bodyweight. A 75kg person needs 225–450mg. Most pre-workouts contain 150–350mg. A large coffee (robusta) delivers about 150–200mg. Start at the lower end if you are caffeine-sensitive.
When should I take caffeine before training in UAE?
30–45 minutes before training for peak effect. In UAE's heat, avoid caffeine within 6 hours of sleep — heat disrupts sleep quality and caffeine compounds this. Train early morning or late evening.
Does caffeine stop working after tolerance builds?
Tolerance to caffeine's alertness effects builds in 7–14 days of daily use. Take a 1–2 week break every 6–8 weeks to reset sensitivity. Even with tolerance, performance benefits partially persist.
Is pre-workout better than coffee for training?
Coffee delivers caffeine effectively at low cost. Pre-workout adds citrulline (pump) and beta-alanine (endurance buffer) that coffee lacks. For most gym-goers, coffee is a legitimate alternative.
