1RM stands for One-Rep Max, which is the maximum amount of weight you can lift for a single repetition of an exercise. It's a key metric for gauging your strength and is used by athletes and trainers to plan effective workouts, as many programs are based on percentages of your 1RM.
Our 1RM calculator uses a scientifically backed formula to estimate your one-rep max without you having to attempt a true maximum lift. You simply input the weight you can lift and the number of repetitions you completed, and the tool provides a reliable estimate.
While a true 1RM test is the most accurate, it can be risky and put a lot of strain on your body. Our calculator provides a very close and reliable estimate. For most users, it's a perfect, safe alternative for tracking changes over time.
Our 1RM calculator can be used for any strength-based lift, including the bench press, squat, deadlift, overhead press, and rows. It’s a versatile tool for gauging your strength in all major compound movements.
This tool helps you lift smarter. Once you know your 1RM, you can use it to set your working weight for specific training goals. For example, if you want to build strength, you can train at 80-90% of your 1RM. If you want to build muscle, you can train at 60-75% of your 1RM.
We recommend using the 1RM calculator every 4-6 weeks to check your progress. This gives your body enough time to get stronger and ensures you are training with the right weight for your goals.
This tool helps you find your maximum weight. The training intensity calculator uses that max weight to help you find the right weight for your specific training goal. Both are great for a complete training plan.
