I'm back to rowing again. My younger brother was staying with us from just before Thanksgiving to just after the New Year, so my Pain Cave became his bedroom. Now that he's gone, it's all set up again for riding and rowing. I've started using a program called EXR for rowing. Very much like Zwift for rowers. It works well with the Concept2 rower and Strava and beats the hell out of just looking at the numbers on the PM5 screen.
