Estimate your 1RM, then choose a better rest interval

This tool turns a recent working set into an estimated max, then maps that intensity to the rest strategy most likely to preserve performance.

Estimated 1RM

262.5 lb

Calculated with the Epley formula.

Relative intensity

85.7%

Based on the relationship between the set and the estimated max.

Suggested rest strategy

Use the 3 minute preset for heavy strength work

This set sits in a high-intensity range where ATP and neural recovery matter more than keeping metabolic stress high.
