Comprehensive bodybuilding competition preparation plan: 12-week cutting program, nutrition protocols, peak week strategy, water and carbohydrate manipulation, and posing practice.

Bodybuilding competition preparation usually takes 12–16 weeks. Effective fat burning without losing muscle mass is the main goal. Body fat percentage on competition day: 3–6% for men, 8–14% for women.
| Weeks | Phase | Calorie deficit | Cardio | Goal |
|---|---|---|---|---|
| 1–4 | Initial | 200–300 kcal | 3x/week x 30 min | Start fat burning |
| 5–8 | Intensive | 300–500 kcal | 4–5x/week x 40 min | ~0.5 kg/week fat |
| 9–11 | Aggressive | 500–700 kcal | 5–6x/week x 45–60 min | Final fats |
| 12 (Peak Week) | Manipulation | Variable | Reduced | Maximum definition |
Peak week is both an art and a science. The goal is to remove the last subcutaneous water, fill the muscles with glycogen and achieve maximum muscle definition. Here is the classic protocol:
| Supplement | Purpose during cutting | Dose |
|---|---|---|
| Whey protein | Preserving muscle mass in a calorie deficit | 30–50 g, 2–3x/d |
| Casein | Nighttime anti-catabolic effect | 30 g before sleep |
| BCAA/EAA | Muscle protection during cardio | 10–15 g before cardio |
| Caffeine | Thermogenesis, energy, appetite suppression | 200–400 mg before cardio |
| L-Carnitine | Fatty acid transport into mitochondria | 2–3 g before cardio |
| Creatine | Discontinued in the final week (water retention) | 5 g/d (weeks 1–11) |
