My studio gives no opportunity to mount pull up bar, and the pull up station takes too much place. I don't want to purchase any big devices because they take a lot of place.
Can I train my upper back muscles with kettlebells, indian clubs, dip up frames or other relatively small devices? What exercises can I use? I've found a lot of exercises for lower back, shoulders or even legs, but not for the muscle parts used by pull ups (maybe I've searched poorly?).
