I belong to the category of mountaineers who used to do rowing for years (15 years of my life).. like Mallory & Irvine, who knew it ?
Imho indoor rowing is good only if you have rowed on a boat and been trained in a rowing club before. Unless you have a very good trainer for indoor rowing. But I rarely see such people out of rowing club themselves.
Last winter I got a discount on the local fitness club near where I live, thanks to my company. There was an ergometer and I saw a couple of people using it randomly, it was painful to watch...
Yes, rowing is a wonderful sport, and nice type of physical effort, but indoor rowing worth only if you are teached...
