Since, I've seen that a lot of moves on dry tooling are about pulling up, locking off on one arm as high as you can then reaching high. Originally I had a loop of rope for one arm training and found that the grip is similar to a leashless axe, so added the two long ropes you see here. From a sit start with feet out, you can grip just above the knots (the knot acts as the horn of an axe,) pull up, lock off and reach high; grip and repeat. You can go feet free if you are strong enough (I'm not,) I have thought of using self amalgamating tape or finger tape to make better grips, but have found them good enough without. https://www.facebook.com/photo.php?fbid=10154156536350445&l=9cfce59090 It's good for those that can only put up a pull up bar.
