Thank you for the form check!
My head stands for 5 sets of 36 felt pretty solid. That was my form for both the strength and mobility element for all 5 sets of each. Although I could do the headstands easily, I felt like my iM form still wasn't good enough (arms not high enough behind me, above my shoulders). I therefore selected "failed mobility" again, to progress only one step in the strength element. Was this the correct selection based on my form? Thank you.
