Woke up and did 4 minutes on the bike to warm my knees up, 35 burpees, some shadowboxing, 2 minutes of fast biking at the 6 resistance, and 15 more burpees. Total workout time was 19 minutes.

Back is feeling a bit better. I found out that it makes a big difference doing some stretching and exercises like reverse crunches and reverse hypers right before bed. That way I'm not going to sleep with any kinks unaddressed that get exacerbated in my sleep. Woke up today not feeling like an old man, for the first time in a few days. 

It makes me wonder about chiropractors. I definitely believe your back can feel better by adjusting it, but how precise can you even be just by eyeing someone? By spinal adjustment I literally just mean stretching myself out and going against extension (hence reverse hypers and crunches), certainly not analyzing individual vertebrae or anything. I've always been skeptical about the practice while also remaining open-minded.

Got a light workout in later by sledgehammering a large shelf and moving debris and an old CRT TV.
