Suddenly tweaked my back twice today at the office! The first time was at my desk when I leaned forward and felt a small twinge. The second was at lunch when I bent further down, clearly not having learnt my lesson the first time, and felt a sharper pain that's now lingering with me. I went for a slow incline walk on the warehouse treadmill afterwards and lay down for 15 minutes for the remainder of my break, dozing off slightly. 

Not sure about boxing today. My instinct is to call it off, but it's a technical day and the easiest day of the week. Might be able to pull it off with my Cerberus soft belt for support. Will evaluate how I'm moving the remainder of my work day and go from there. It costs $15 to cancel a class if it's less than 24 hour notice, which is my only annoyance about this gym. Will definitely cancel tomorrow's class, though, which typically has a lot of conditioning.

 Felt sick and rundown, so last night I worked up to squatting 405x5 with the Yukon bar and called it there. Every rep felt awful, but equally so - the 5th was just as hard as the 1st and I could have kept cranking out reps, but knowing I haven't been sleeping great and with 2 days of boxing ahead of me, 5 was just the right amount.

Why back to the curved bar? Low bar squatting has been starting to hurt. My elbows are no longer feeling the strain, but lately I've been feeling discomfort on pressing exercises that feel like accumulative punishment from squats. Rotating different bars and bar placements is needed.

I am also going to bring back scheduled deloads. There have been countless times running 5/3/1 where I came back after a deload and marveled at how much better and stronger I felt.
