Who Should Use the One Rep Max Calculator?
This calculator is perfect for weightlifters, bodybuilders, and strength athletes aiming to determine their maximum lifting potential for any given exercise. Knowing your one rep max (1RM) is essential for setting appropriate weights for different training goals, such as endurance, hypertrophy, or maximal strength.Understanding the Formula
Where:
– 1RM is the estimated one rep max,
– W is the weight lifted,
– R is the number of repetitions completed at that weight.
This formula provides a reliable estimate of your one rep max, especially when performing 3 to 10 repetitions. It accounts for the fact that as reps increase, the effective max weight decreases.
How to Use the Calculator?
- Enter the Weight Lifted (W): Input the weight you used for the exercise.
- Enter the Repetitions Completed (R): Specify the number of reps you performed with that weight.
One Rep Max Example
Here’s an example of how it works:
– Weight Lifted: 80 kg
– Repetitions Completed: 5
Using the formula
1RM=80× (1+5/30) =80×1.1667=93.33 kg
This person’s estimated one rep max for that exercise would be approximately 93.3 kg.
Tips for Maximizing Strength Gains
- Use your 1RM to Plan Workouts:Calculate percentages of your one rep max to set training weights for different goals, such as 60% for endurance or 85%+ for strength.
- Prioritize Proper Form: Always use proper technique, especially when lifting near your max, to reduce the risk of injury.
- Track Progress over Time: Monitoring changes in your one rep max is a great way to assess strength gains and adjust your goals.

You can test it by increasing the load on the barbell until you can’t lift it – then, the last successful attempt determines your 1RM. Alternatively, find a weight that you can lift 2-6 times and calculate your predicted one-rep max, for example, using the Epley formula.
Generally, not more than once every few weeks. It should be even less frequent as your fitness level increases – the heavier the weight, the more rest your body needs between the tests.
There’s no set value you should compare yourself to. We all have different body types, and your performance also depends on other factors such as sleep, nutrition, or even the weather. Aim to be better than your past self!
To find your max deadlift, find the maximum weight you can lift 1-10 times and multiply it by an appropriate NSCA coefficient. They are specified for different lifts, so the results may be more accurate than if you used a general 1RM formula such as Epley or Brzycki.
