NASM's One Rep Max Calculator
Calculate your one rep max (1RM) for any lift. Your one-rep max is the max weight you can lift for a single repetition for a given exercise. To lift safely, a one rep max calculator is essential for determining what you can handle on the squat rack, bench, deadlift and more.
A one rep max is also a huge factor when training in the Maximal Strength phase of the NASM OPT™ Model - as the weight ranges will sit in the 85-100% range of your 1RM. Being able to gauge the correct weight to lift will help keep your workouts intense enough to develop strength.
Once you input the totals of your lifts, you will see a table of ranges that will determine where you are regarding your max lifts. Remember to calculate your 1RM for every specific lift. You don't want to assume that your bench press max will carry over to your back squat max.
Remember, the values are only estimates. Be sure to consult a personal trainer - or become one yourself - to ensure you are lifting safely. Check out our other fitness calculators as well to get the clearest picture of your overall fitness level: BMI Calculator and Calorie Calculator
