It's kind of a standard in the sport science world where you have a bar and you basically calibrate the machine to where um the bar is about the mid thigh and is almost like the the very top of a deadlift and you just pull but the bar doesn't get to move. And the sensory input is like the force decks and they're and they're measuring your balance of your force and all these other cool metrics. But holding that over time, we're now isometrically loading the heck out of my grip. We're loading the heck out of my shoulders. We're getting into my feet, my quads, my hips, and I'm just holding that for time.
