I've always heard you can hurt yourself badly if your form isn't perfect, esp your back. True? If so, how do you help people maintain good form and not screw up their back?
Like with any workout injuries are always a possibility. We do our best to mitigate this with instructional videos for novice users and automated feedback (for example when the user is going too fast). That being said, stationary rowing machines, found in gyms or homes are not generally associated with a high risk for injuries.
