So I failed this. Basically I overtrained badly and then couldn't recover quickly enough in the timeframe. I also compromised all my other training, which slowed my progress even further. Funnily enough right after I stopped worrying about one arm chin up my other skills suddenly improved a lot. My front lever is much more solid, tuck planches are longer and I can now do Stalder press which I couldn't do before... Anyway, I'll work on the one arm negatives as part of my training and eventually I'll get there. I will also do low intensity high rep workout once a week to help me with recovery and injury prevention.
Another video from my one arm chin up training. The weather's been a bit shitty but managed to get some footage yesterday.
Not the best day though, you can see a lot of jerking around, the negatives should be slower and more controled. I was really struggling with the one arm chin up holds using my left arm which I didn't have a problem with last week. I was also hoping I could fit a lot of rope climbs into my training but the weather didn't permit. Anyway will stick to the holds and negatives and see how it goes. I will also finish off each session with chin ups holding the forearm.
