RackMath Barbell Calculator 4+

When you’re in the gym, you want to focus on your workout. You don’t want to spend time calculating which weight plates you need to load onto your barbell. RackMath is the simple solution to this problem. It will handle all the plate math for you.

FEATURES

Quick:
Stop doing the math in your head. RackMath calculates the plates you need instantly. Perfect for heavy lifts like the squat, deadlift and bench press.

Safe:
Don’t step into the squat rack with the wrong weight by accident. You can count on the RackMath calculator to make sure you’re loading your bar correctly.

Customizable:
Not everyone has the same set of weight plates. This is why RackMath is designed to let you set your own equipment inventory. Select pounds or kilograms and choose the plates available to you.

Fractional and non-standard weight plates:
Other weightlifting calculators do not include fractional plates or lesser used weight plate denominations. RackMath's inventory offers fractional plates as well as a large number of denominations.
