Move well. Then know your numbers.
Training isn’t just workouts. It’s the seven movements life asks for every day, and knowing what the numbers mean when you load them. Every calculator here runs on one engine, so the site and the app never disagree, and every result tells you how far to trust it.
Before the numbers
Seven movements to master.
Picking up the box, pushing the couch, walking to the store. If I could only train a handful of movements for the rest of my life, these are the seven, why, and the five-minute practice that keeps each one.
