During my usual lunch break walk yesterday, I went all the way to the trail's pull-up bars and did a 60 second dead hang.
Day 2 out of 4 at the boxing gym yesterday. My body was hurting: lower back from tweaking it last week, right glute, and left lat which suddenly burst into pain when I was microwaving breakfast yesterday morning. On the upside, my elbow has been feeling MUCH better and my left shoulder is improving. I didn't have any problems when it was time to perform. Worked with my partner on trading combos and did a good job of staying relaxed.
For bagwork, I took off my new Ringside 16 oz sparring gloves, which are comically big and pillowy even for 16 oz, to don my bag gloves and it was like I had super powers with the smaller gloves.
Before bed, I switched my foam mattress from the firm side to the soft side and sure enough, woke-up today with my back feeling like it was recovering. This seems to be the pattern that works: firm side for most nights, but when I have tweaks or injuries, the soft side makes me feel better for a few days before it starts to feel like my back needs the extra support again. Very interesting.
