Mastery of strength but not mobility

Hi, quick question. If I am mastering scapular shrugs, but I can't keep my glutes on the ground with swivel hips, should I stay in PE1 until I master mobility? It seems like it could be a while. 

Hi Sebastian, yes this is the first rule fo foundations. mater both mobility and strength before moving on.

Thanks! 

you are welcome.

It's going to take me close to a year to master hip swivels! Impossible to keep my glutes on the ground...

Probably you have an internal rotation deficit. my suggestion is trying swivel hips daily and if necessary helping the knee to reach the ground with one leg...slowly gentle push.
