Due to certain circumstances involving travelling, I won't be able to hit up the gym for a while. But as I want to stick to some sort of regularity, I've come up with something of a routine to minimize losses.
I will have no weights whatsoever, so I will be forced to use my bodyweight for everything. I'll be in a hotel room, so I won't have a pullup bar. Does anyone know any good excercises for the back, with these limitations????
