The basics

Suffering after a night of insomnia, I struggled to find the motivation to do this rather than lay on the couch:

Five rounds:
2:20 min row (about 500 m)
5 push-ups
15/leg Bulgarian split squats

Plus 12 knee push-ups at the end. Jeez, push-ups with your hands under your shoulders are hard.

I didn't time it precisely, but it seemed to take about 25 minutes.
