I've wanted stall bars for a while, but don't really have the room in my small apartment. I managed to jury rig this on my punching bag stand using a few wooden boards, a rope ladder I had laying around, anchored it with rope and a couple of well placed knots.
I feel confident enough in my rigging ability that it's stable, and going to drill some anchors to secure the rope ladder a little more to prevent it from moving. The best part about it is I can quickly take it down when I don't need, and store it out of the way.
Not the greatest setup, but making the best of what I can right now. Just wanted to show that a little ingenuity can go a long way.
