I'm actually thinking of their treadmill, which
is $4K. But okay, fine; it's "only" $2K. My question is just as valid: "on a $2K machine? My half-that-price rowing machine can adjust resistance on the fly."
Hell, the pricey-but-not-as-pricey-as-Peleton computerized trainer I had almost 15 years ago could adjust the resistance on the fly. I just figured that was table stakes these days.
