I'm going to repeat a microcycle of this one as well. My ROM is actually pretty good... at the start, but then the in the last seconds of the last set I'm barely arched at all, so I've technically failed 5x36 s.
I'm starting to thing that having a hot plate in front of my face might work as incentive
.
Now seriously, there are two things that are helping me in this exercise:
Focus on breathing correctly, shallow but steady breaths. One will never get 5x60 seconds of anything without breathing correctly I think. I find that focusing on breathing helps me not focus on how much the holds sucks
. The other thing is, not only arch your body, raise heels and hands but also press with your belly, like I assume is what will be your pivot point when one graduates to AB rocks. This is tricky to do with and keep the breathing but I feel that I'm getting better at it and I find it helps with ROM. So now for me is really a matter of endurance.
