Cross training
Last night, Nathalie didn't feel like riding her exercise bike. I decided to ride it for a while.
My resting heart rate then was lower than yesterday morning, 47 bpm. I rode for 45 minutes, aiming for the low end of my aerobic zone, actually averaging 134 bpm, about 72% of my maximum heart rate. The readout said I burned 586 calories.
Maintaining an aerobic training pulse on Nathalie's exercise bike turns out easier said than done. It would be more straightforward on a trainer where the resistance increases with speed.
