Could have did a better job at locking out the knees (thought they were locked out anyways). Based on self-judging, I give myself 2 out of 3 white lights.
No thumb damage. I applied vaseline at the end of my thumbnail (where the nail normally digs into my skin, cutting my thumbs).
Ever since I started taking strength training seriously, I was bitten by the Iron Bug. Then it burrowed under my skin and laid eggs in my heart. Now those eggs are hatching and I... the feeling is indescribable.
