4.5 Safe to install
1RM Calculator is a valuable tool designed to assist you in determining your 1-rep max. This utility allows you to input the weight you successfully lifted and the number of reps you performed, providing you with an estimated 1-rep max.
By utilizing this calculator, not only can you gauge the weight to attempt during a 1-rep max, but you can also assess your strength and compare different rep schemes at varying weights. For instance, if you were able to bench press 190 lbs for 6 reps one week and then 200 lbs for 5 reps the next week, this application enables you to make a close comparison (190 lbs @ 6 reps gives a 1-rep max estimate of 223 lbs, while 200 lbs @ 5 reps gives an estimate of 227 lbs).
