A Training Max (TM) is a sub-maximal weight used as the basis for your daily workout calculations, rather than your true, all-out 1RM. It's a core concept in many popular strength programs, like Jim Wendler's 5/3/1. Using a TM (typically 85-95% of your 1RM) allows you to train with appropriate intensity while managing fatigue, reducing the risk of injury, and promoting more consistent, long-term progress. This calculator makes it easy to find your TM based on your true max and desired percentage.
