I tried PE4 for the first time yesterday, and it looks like I could hit mastery on first go (I'll post a form check to be sure).
Well, for the PE at least. For the iM it goes pretty much as with PE2>iM: with around 2kg my form is good, with 3 is acceptable, with more it is not.
(On a side note it does not help that in my gym I can use either 1.5 kg, which is a bit light, or 4.5, which is a bit heavy, especially if my shoulders are not absolutely fresh).
So, shall I move to PE5 on the basis that I can have acceptable form with up to 3kg, or take the chance to work on getting comfortable with higher weight?
I suspect the latter is a better idea. If so, any advice for specific exercises to strengthen the right muscles and hopefully hasten the process, besides the iM itself?
I feel the problem is strength at end of ROM rather than mobility as with less weight I can demonstrate full ROM.
