What is One Rep Max?
The One Rep Max (1RM) is the maximum amount of weight you can lift for a single repetition of an exercise. It’s a critical metric used by strength athletes and trainers to gauge overall strength, assess progress, and tailor workout programs.

Why Calculate Your One Rep Max?
Knowing your one rep max has several benefits:
- Optimized Training: Design workouts based on percentages of your 1RM to target specific goals like strength, hypertrophy, or endurance.
- Tracking Progress: Monitor how your strength improves over time.
- Setting Safe Limits: Avoid overtraining or risking injury by understanding your lifting capacity.
How Accurate is the One-Rep Max Calculator?
The one rep max calculator uses established equations like Epley’s Formula and Brzycki’s Formula to estimate your 1RM. While the calculations are highly accurate for most lifters, factors such as experience level, fatigue, and technique can influence the true max.
Popular Exercises for One Rep Max Testing
You can calculate your 1RM for various exercises, including:
- Bench Press
- Squat
- Deadlift
- Overhead Press
These are the most common lifts where 1RM values are used to measure overall strength.
Tips for Testing Your True One Rep Max
If you plan to test your 1RM in the gym:
- Warm Up Thoroughly: Prepare your muscles with lighter weights before attempting a max lift.
- Use a Spotter: Safety comes first, especially for heavy lifts like bench press or squat.
- Focus on Form: Ensure proper technique to avoid injuries and get an accurate measurement.
1RM Training Percentages
Once you know your one rep max, you can base your workouts on these percentages:
- 50-60% of 1RM: Endurance training
- 70-80% of 1RM: Hypertrophy (muscle growth)
- 85-95% of 1RM: Strength training
- 100% of 1RM: Maximum strength testing (rarely used in regular workouts)
