Well, good eating and good sleep has brought back my strength and then some!
I busted out 6 tempo HeSPU with ease, I didn't go for more. I did two more sets, all of which were submaximal.
I also played with squats. With no warm up, and without having been under a bar for months, 275 was laughably easy. I was shaky because I'm detrained, but the weight felt really light! I did two easy reps and racked it. I then did front squats with 135, pretty light, but my form felt perfect! Quite exciting! I'm going to work these back in once a week, along with a little thick bar bench pressing once every week or two. I seem to be making my best gains with a combination of 20-30% weights and 70% calisthenics, as a total volume breakdown.
