A slow leg lift while breathing on a count and trying to keep your lower back pressed to the mat, and your whole core shakes by the third rep. It looks gentle from the outside and humbles you in private. You'll leave wondering why something that quiet was so hard.

The shaking gets less embarrassing. You start to feel which muscles are actually supposed to be working instead of the wrong ones compensating, and a few moves that felt impossible in week one become almost controllable. Your posture changes slightly and someone else notices before you do.

There's strength in places you never paid attention to, like your deep stabilizers, your hips, and the long muscles along your spine, and it shows up in ordinary life: standing longer without shifting, sitting at a desk without slumping forward. Progress is quiet, but it's real and it sticks.
