I had a quick hour between work and OT last night. Since I'm in the work gym, which is only really a Smith-like and some dumbbells, I did a back/bi. Impressed myself that I'm starting to see some development just in the controlling muscles of the arms. Also, to finish hard, I did progressively higher-weighted curls. Expecting to fail at about 4X, I went consistently to 6X, and probably the most I've curled in many a moon. My 10" guns looked almost 11" at the end
