So, after two days off from the gym, walked in today tired as hell after sitting at a desk for 10 hours (bad) mostly doing necessary but slow-going database transfer work (worse). Had little energy, so I decided to forgo the cardio, even for a warmup, and hit bench, back, and deads (because I felt like it).
Hammered out some incline bench (shoulders and tris are weak), some dumbbell flies, military press, dumbbell rows, narrow grip rows, and barbell rows. Even did some curls for the girls (to protect my biceps when DLing... oh, who am I kidding, I want bigger arms). Thought I would hit some light deads for speed work... and then ego took over. Kids in the squat rack doing 315 pound half-shrugs to show off for their girlfriends were kind of pissing me off (as usually happens when I watch silliness in the gym; I can't help but feel like the gym should be serious business, and after a long and mentally draining day I get irritated pretty easily), and after 225, 315, and 365 came up like rockets, I decided to go heavy. Hit 415... that came up fast too. Hit 455... easy.
Slapped 20 more pounds on and went for a 20 pound PR.
Came up smoothly... I can't say easily, but as soon as the bar broke the floor it was one steady movement, constant speed, no hitch.
Long story short, my day got much better.
