Okay, I did 175 push ups on Saturday and on Sunday I was feeling it. How did I recover? I stretched my pecs and worked my upper back muscles. The opposite group that I worked in the push ups. I also had a headache. Part of my headache was allergy related and the other was probably not holding my head up through all of those darn push ups. In other words: bad form! At least for part of the push ups, the second half most likely when I was in muscle failure.
I used a skinny (light weight) pull-up band to strengthen the muscles between my shoulder blades. The muscles that pull my shoulder blades towards my spine.
I also did a bunch of bent over reverse flies without weight….like 5 sets of 50. This was a stretch for my pecs and shoulders. Also it worked the posterior shoulder and upper back. I wanted to pull my body out of the front body (chest and shoulder) tightness that I had created with all the push ups.
Doing the reverse flies like this also helped pull my head back into alignment. I felt much better after doing these!
