User Reviews

Simple to use and is a great training tool.

I’ve personally used 7 different maximum lift calculator apps. This is the only app that I will trust when calculating an anticipated maximum bench press. It has yet to fail me. For example, with no spotter (with safety catches) I easily benched 235 x 8. Within the next few days I benched 282 with relative ease.
