Estimate max capacity and generate intensity-based programming targets.
Performance Architecture · Strength Science
Know your max.
Programme with precision.
The Epley formula uses a submaximal effort to estimate your one-rep max without the injury risk of true maximal testing. Enter the weight you lifted and the reps completed — the calculator generates a full percentage-based intensity table for your programming.
