That little stretch my physio showed me is a game changer for edge sanding

I was getting this sharp pain in my forearm after sanding the edges of my projects for hours... thought it was just part of the job. My physio friend saw me wincing and taught me to extend my arm, palm down, and gently pull back on my fingers for thirty seconds. I do it before I start now, and during breaks if it's a big batch. The pain is basically gone... and I don't feel as tired by the end of the day. It made me think about how we ignore small aches until they become big problems. For folks doing detailed work with their hands, these tiny habits might save a lot of trouble down the line. I'm way more mindful about my posture and taking short pauses too.
