Frequently Asked Questions
How accurate are bench press max calculators?
1RM calculators are most accurate when using sets of 1-10 reps. Accuracy decreases with higher rep counts. The Epley and Brzycki formulas are typically accurate within 5% for low rep ranges.
What is a good bench press for my weight?
Beginner: 0.5x bodyweight, Intermediate: 1x bodyweight, Advanced: 1.5x bodyweight, Elite: 2x bodyweight. These are general guidelines and vary by age, sex, and training experience.
What is the difference between Epley and Brzycki?
The Epley formula (1RM = weight x (1 + reps/30)) tends to estimate slightly higher for more reps. The Brzycki formula (1RM = weight x 36/(37-reps)) is more conservative. Both are well-validated for lower rep ranges.
