Basement: Back to Basics

Every time I take off my shirt, it's clear I need to do more sit-ups.

10 rounds of:

10 calories rowed
10 push-ups
10 sit-ups

13:11  

If I was to do this again, I might switch it to five rounds of 20.   I suspect the time would be longer, even if there was less time transitioning on and off the rower, as muscles would fatigue more quickly
