Como Estimar

Fórmula de Epley: 1RM = Peso × (1 + Reps/30). Se levanta 80 kg por 8 reps: 1RM ≈ 80 × (1 + 8/30) = 101 kg. Mais precisa com 3-10 reps. Acima de 12, resistência muscular distorce a estimativa.

Percentuais de Treino

Força: 85-95% do 1RM, 1-5 reps. Hipertrofia: 65-80%, 6-12 reps. Resistência: 50-65%, 15+ reps. Conhecer seu 1RM permite programar a intensidade com precisão.
