If you prefer a calculator that simply performs calculations on one of the three big three you may like to visit: http://functionalstrengthlab.com/workout-calculators/big-3-calculators, or http://functionalstrengthlab.com/workout-calculators for the same calculators, but with a more thorough description for beginners.

While having average, or above average numbers in these lifts may represent a “strong” individual in some circles, please note that we at Functional Strength Lab do not equate these numbers directly to functional strength. However, the bench, the squat, and dead lifts do in fact require a tremendous amount of power and explosion, that are valuable in many sports. For this same reason, it is also extremely important to know it is not essential and is oftentimes detrimental to actually push yourself to your 1RM. This is one of the added benefits of this calculator. You only need to know what weights you typically perform for reps, and through the research of seven different strength professionals you can estimate your 1RM.
