I read through the long sticky post on shaking.
Coach said shaking indicates that shaking means mastery has not been achieved. On FL/PE1, my abs start shaking after a few seconds, but I can complete 5x60s without much trouble (unless you consider shaking to be trouble).
To confirm - does any shaking mean no mastery?
Here's a video of 40s or so of my FL/PE1 (shot after completing 5x60s):
My abs are shaking pretty much the whole time, but it's not that visible from this shot.
So just for clarity - what level of shaking is considered acceptable / non-acceptable for mastery standard?
Thanks!
