The past paragraph is funny to me - in my experience the same wattage is much easier on a rowing machine exactly because it uses more muscles. Sure I’m primarily using my legs, but they get a slight rest each cycle when I’m at the tail end of the stroke and using arms/back.

For 1 hour FTP in heavy trading training, I did about 250 watts rowing and 300 watts cycling. I did 250 watts on the bike for about 6 hours, and I don’t think I could have done 200 watts for 3 hours rowing for several reasons.

I think the best multi-hour total energy yield efforts are from recumbent bicycles.
