Hello,
If I am at the last step of progressions for an exercise, but then fail to accomplish real mastery (maybe because the iM isn't as good as it should be, maybe because the form is not perfect yet because of lacking mobility, should I then keep cycling the last 4 steps over and over until I master it? Or just repeat the last step of the exercise except for the deload weeks?
And a related question: should I even go to the next step of an exercise if the form is not as it should be?
