What is this calculator? This One-Rep Max (1RM) calculator estimates the maximum weight you can lift for a single repetition of any given exercise.
Why use it? Knowing your 1RM helps you create accurate strength training plans, set realistic goals, and track your progress efficiently.
Benefits: Helps you lift smart, avoid injury, apply progressive overload, and customize training percentages (e.g., 75% 1RM for hypertrophy).
