I think it's a no brainer that the treadmill and elliptical are the most popular machines at the gym. They are usually more treadmills and ellipticals than other machines and they're the only ones I ever see people waiting in line for. I'll even admit that I have a tendency to always book it to the treadmill.
Not too long ago I went to the gym and there was a huge line for the treadmill. In an effort to save time I used the rowing machine instead. I was surprised that more people weren't going to other open machines like the stationary bikes or stair climber.
Tell me . . .
