So it has been one year since I started ABH on regular basis. Today I finally was within touch of mastery 4x60 sec and failed last 15 sec of set 5. I was still able to hold my feet up but rib cage slowly came down... damn gravity.
Sticky post by wheezer was invaluble, one by one I learnt how to implement all his and other tips from his thread. Thanks a lot to everyone who contributed to it!
But few things I had to do differently from what is recommended by GB. I guess everyone is different and some things might need slight personal modifications. I was wondering anyone else noticed similar simptoms. I can't even count how many times I tried to transition from week 7 to 9 and failed to get even close to week 9 requirement after relatively easy week 7. It took time for me to figure out that rest week 8 was the problem. So instead of doing 50% week 8 I would just take few days longer break and instead of doing ABH every 4-5 days I would rest 5-6 days do the same week 7 sets rest 5-6 days more and go straight to week 9. That helped to keep up with week 9 but then I was stuck at week 9 for months before finally I tried high rep approach a couple of months ago and that helped to push past week 10.
So what I am trying to say is it seems that at least in my case ABH required very consistent hard work on very strict schedule. Little more and I would get over trained, little less and I would loose it again.
