I like this answer. Good cardio, good for the core. Full body exercise. Rowing machines the best machine imo. Also quite hard to fuck up on or hurt yourself with, in my experiance.

Lots of movement in many joints too.

I tried a rowing machine, would never do it a second time. Now, I have bad knees, but I still thought it wouldn’t be that bad. Maybe it was a bad machine, maybe I used it wrong, maybe they aren’t for everyone.

I’d be afraid of putting myself to sleep with it.
