American Ninja Warrior - Things that are holding me back - #2

All my problems are tendonitis-y, I also have RSI but that doesn't really affect this new crazy goal of mine. Golfers Elbow in my right arm is a big problem though, it started when we were touring around Spain. I had been going to the gym heaps before we left, and then while we were bouncing around that crazy hot country, I'd only sporadically get to a gym... I tried my normal pull-ups and my elbow did not like it one bit. It's been a problem for nearly 10 years now. Basically Hammer Curls are impossible, and pull-ups develop an ache pretty quickly.
