I’ll do a quick “bug scan” every 30 seconds—check that the shoulders stay relaxed, the knees don’t buckle, the hips stay level, and the breathing is even. If any of those markers slip, I pause, reset the form, then resume. I also jot a one‑line note in my routine log and, if I’m still unsure, I film the clip and play it back to catch subtleties my brain might miss. That way the small quirks are fixed before they grow into aches, and the routine stays as clean as a puzzle piece.
