Reps Calculator - Utility for estimating your 1-rep max!

Reps Calculator is a tool to help you determine your 1-rep max Because of the nature and stress of attempting a 1-rep max, this utility allows you to enter in a weight you successfully lifted at the number of reps you performed in order to see what your estimated 1-rep max is. This not only helps give you an idea of the weight to attempt when actually performing a 1-rep max but also to gauge your strength and compare different rep schemes performed at different reps. Always ensure you have a spotter, and work your way up to your limit with more than adequate warmup to prevent injuries.
