I am working like a dog and in addition to my low back my neck is sore as well. Today I decided to do pushups after every patient I attend to. The reaction of my staff was amused and funny at the beginning. After several sets however one young nurse joined me and did a set too. It feels good: less of the tired feeling in the shoulders at the end of the day.
Pushups - 7 sets of 10 in variations
BW squats - 2 sets of 15
