Step-by-Step Worked Bodybuilding Example

Consider a 30-year-old male lifter weighing 80 kg, 180 cm tall with 15% body fat, and tested lifts of 100 kg Bench Press, 140 kg Back Squat, and 180 kg Deadlift (performed for single repetitions):

1. Body Composition & BMR:
BMI = 80 / (1.80)² = 24.69 kg/m²
Lean Body Mass = 80 × (1 - 0.15) = 68.0 kg
Normalized FFMI = 68.0 / (1.80)² + 6.1 × (1.80 - 1.80) = 20.99
BMR = 88.362 + (13.397×80) + (4.799×180) - (5.677×30) = 1,853.6 kcal/day
2. Big 3 & Progression:
Big 3 Total = 100 + 140 + 180 = 420.0 kg
Strength Ratio = 420.0 / 80 = 5.25x Bodyweight
Weeks 1–4 Bench (70%): 100 × 0.70 = 70.0 kg (10 reps, 14 sets)
Weeks 5–8 Bench (75%): 100 × 0.75 = 75.0 kg (8 reps, 12 sets)
Weeks 9–12 Bench (80%): 100 × 0.80 = 80.0 kg (6 reps, 10 sets)
