Firstly, I'm glad that there's a call out made on tall girls having more difficulty with this. I've always wondered whether having disproportionately long legs and being 5'8 has stopped me from getting moves that tinier and weaker girls I know have gotten no problems 🤔 Also every SINGLE masterclass I've done (pantera, allegra, deb riley, suzie q, alethea et al) are either teeny tiny or on the short side. The only tall girl I know of that is an amazing dancer is Fleur/Amber
I think the mule kick/swing into this move is dangerous, it really pulls the arm out of the shoulder joint and just does not feel healthy. In fact for this move, right from the first leg lift, so many muscles and limbs need to be fully engaged, I dont
In saying that, once your strength builds up, I have found that when starting the move, pushing a lot with the bottom hand/pulling a bit with the top hand, then as you rise, pull a lot with the top hand/push a little with the bottom, really helps.
And also try not to fully lock your elbows out on the bottom arm, as this will lessen the engagement of the upper arms/shoulders.
