sPL SE5

I am having a lot of trouble building up to the 5x30 of mastery. Once warmed up my first set I can usually only get 12-15 seconds. I have tried them on the floor and on pbars. It seems that I can't keep my forward lean and my legs begin to droop to my elbows. What else can I do to build up the necessary strength here? Are there any other supplemental exercises I can do? It's killing me and I'm getting really discouraged.

I'm not on this element yet but as a general principle if I advance to an element and I really struggle on it then I question my mastery standards of the previous one (or more) elements in the same family. How is your SE4?

The F1 spl mobility exercises cover this motion /activation pretty well. Id revisit them in my warmup if I were you, maybe play with moving the support higher on my body than required for F1 to put more demand on extending the whole lower back/hip area

(Naturally you could put this motion on a bent arm pl if you wanted more upper body too )

As it turns out I have decided to knock my self back down a few rungs to sPL SE2. We'll see what happens.

sPLSE5 doesn't require 30s for mastery. Are you sure you are talking about that progression?

Mastery
To move to the next progression, you must be able to perform 5 sets of 10r (alternate legs) along with the coupled mobility.
