Early on you're stuck on what looks embarrassingly basic, like a single clean pull-up or a push-up that doesn't sag, and progress comes in frustratingly small increments.

There's no machine to hide behind; it's just you, gravity, and the honest feedback of a movement you can't yet do.

The reward is strength that feels usable and earned, plus the slow thrill of unlocking skills like the first time you hold yourself off the ground.
