Skipping light day was a bad idea.

Squats 1 x 12 x air, 1 x 10 x 45, 1 x 5 x 65, 1 x 5 x 95, 1 x 3 x 115, 1 x 3 x 125, 1 x 3 x 135, 2 x 1 x 145, dumped the second rep on the rack, helped replacing it while loaded and tweaked my left lat hard. Unloaded the bar, did 5 reps or so, didn't keep track, with the empty bar to see how my back was. It wasn't too bad, so I did 5 x 5 x 115. Hyperextensions 15.
Overhead press 1 x 8 x 45 while I decided what to do next, still paying attention to my back, moved on the bench press. 1 x 10 x 45, 1 x 5 x 65, 1 x 5 x 90, 1 x 3 x 90, was going fine here until I hit the rack. 1 x 4 x 90, 1 x 4 x 90, 1 x 3 x 90, 3 x 5 x 85.

15 hyperextensions, deads; 1 x 3 x 135, 1 x 1 x 160, 1 x 1 x 170, 2 x 1 x 180 YAY ME! They may have been ugly, I don't know having not brought my camera, but they went up. 2 x 3 x 160, had to switch to mixed grip on the third rep of each set. 15 hyperextensions and out.

I'm aiming for both Spin and yoga tomorrow, then doing a light day for real on Monday.
