As mentioned you are wrong on this: rowing is mostly legs, some core muscle and then a little arm. As you don't have your full weight on your knees it is a good way to get started on working your legs when you're overweight.

As someone who rows an actual boat once or twice almost every other summer I just want to say that rowing is mostly upper body and arms, with little to no legwork.

I guess we're not thinking of the same thing when writing about rowing.

I'm thinking of this: https://en.wikipedia.org/wiki/Rowing_(sport)#/media/File:Avi... and if you do little legwork you're doing it wrong.
