Understanding Your Bench Press Max
What is 1RM?
One Rep Max (1RM) represents the maximum weight you can lift for a single repetition with proper form. It's a key metric for strength assessment and program design.
Calculation Method
This calculator uses the Brzycki formula: 1RM = weight × (36 / (37 - reps)). It's most accurate when using weights you can lift for 1-10 reps.
Safety First
Always warm up properly, maintain good form, and use a spotter when attempting heavy lifts. Stop if you experience pain or discomfort.
