FAQs
What is a One Rep Max (1RM) and why does it matter?
Your One Rep Max, or 1RM, is the maximum weight you can lift for a single repetition with proper form. It’s a benchmark for strength and a critical number for designing training programs. Knowing your 1RM helps you set realistic goals, track progress over time, and adjust your workouts to push past plateaus. Even if you don’t test it directly in the gym, our calculator estimates it safely using proven formulas.
How accurate are the 1RM formulas used in this calculator?
We use well-respected formulas like Epley, Brzycki, and Lander, which are widely accepted in the fitness community for estimating 1RM based on submaximal lifts. While they’re not 100% precise—since factors like fatigue or technique play a role—they’re incredibly close for most lifters. Testing with different weights and reps can help refine the estimate, but these methods give a solid starting point.
Should I test my 1RM in the gym or use a calculator?
Testing your true 1RM in the gym can be risky, especially without a spotter or proper preparation, as it pushes your body to the limit. Using a calculator like ours is a safer bet—you can estimate your max based on lighter lifts without the strain. It’s perfect for beginners or anyone planning a program. That said, if you’re experienced and have safety measures in place, a real test can confirm your numbers.
