Back was feeling much better today in warm-ups, but by rep 8 of squatting with 320 I shut things down. No further injury, just increasing feelings of discomfort that told me better safe than sorry. It's definitely progress to get some load on my back again.

Mountain climbers have been a great all-day practice to keep things moving in a positive direction. They loosen things up and my knees always appreciate doing them too.

I'm thinking I'll do a belt squats at night after work and maybe bust out the Prowler after.
