• Lombardi–weight × reps ^ 0.1
• Epley–weight × (1 + 0.0333 × reps)
• Wathan–(100 × weight) / (48.8 + (53.8 × e ^ -0.075 × reps))
• Brzycki–weight × (36 / (37—reps))
• Mayhew–(100 × weight) / (52.2 + (41.9 × e-0.055 × reps))
• Lander–(100 × weight) / (101.3–2.67123 × reps)
• O’Conner–weight × (1 + 0.025 × reps)
