His legs were shak­ing before he even went down into the next squat. He stood in front of me at the wall ball sta­tion with that look peo­ple get when they are no longer real­ly decid­ing any­thing. They are just try­ing to keep the body mov­ing for one more rep, then one more, then some­how anoth­er. He picked up the ball, dropped down, came back up, threw, caught it. I watched the move­ment and called it straight away: no rep. Not because he missed the tar­get. Because he had not gone low enough.
