“They have one of those in the back.” Most gyms have rowing machines. It’s just they’re hidden in plain sight because they’re not glamorous devices. Running is sexy. Rowing is… not. One treadmiller had rested his backpack on the sole rower at this one gym, and when I motioned that I wanted to use it, while courteous, he seemed surprised that someone was going to use it. See, I don’t like rowing being my secret.
