Gyms in Tokyo with rowing machines near Hibiya line?

Hi everyone,

I’m looking for gyms in Tokyo with rowing machines. I currently go to Flux Conditionings in Daikanyama, but I moved further away and it’s a bit of a hassle to get there and then walk another couple of minutes. I’ve also looked inside CrossFit Daikanyama, but it smelled a bit foul when I asked to look inside.

Does anyone have any recommendations along the Hibiya line?

The Andaz AO spa has one, but the initiation fee and insurance deposit are not worth it to me, especially given that the gym itself is pretty small. The pool is nice, though.
