Rich - your post highlights the rich opportunity in high-rep training. In my experience, the high rep sets offer a different and unique opportunity to work with the body-mind. Your blog/post highlights the dialogue and tension between the emergence of our fundamental conditioning to avoid pain and our intention. 

Stay Strong! 

I've shifted all of my training the past 2-3 months to 20 reps and I'm absolutely loving the dance between this “conditioned avoidance” and the intention and commitment to remain present, engaged and open until I hit 20 or momentary muscular failure. 

Stay curious amidst this dialogue and tension, personally I've noticed some remarkable shifts in consciousness and my body-mind's ability for engagement and “out put” when I remain curious and open to the space in which all of this is arising. 

Peace Gents - Happy holidays to everyone
