Calculators coaches actually use

Free, fast and mobile friendly. No sign-up, no email wall. Use them, share them, link to them.

One rep max calculator

Estimate your 1RM from any set. Enter the weight you lifted and how many reps you got, and see your max plus a full training percentage table.

Get your daily calories and macros in seconds. Built on the Mifflin-St Jeor equation, the most validated formula for resting energy.

Work backwards from the income you want to the price you should charge. Most coaches undercharge because they price from fear, not from math.
