Swivel Hips sPL/PE1>iM help

I seem to be missing a lot of internal rotation RoM in both hips to the point where I can't properly perform the first mobility exercise in the sPL progression (Swivel Hips).  

 

Should I just keep on trying the swivel hips movement without being able to get anywhere near getting my knees to the floor while my glutes are on the ground or is there a better supplementary mobility exercise I should try help out my hip mobility?

From a simialar thread in h1 forum. Helps alot.

You could consider doing some supplementary stretching of the piriformis.

 

Definitely support what Soye Boy posted.  Don't try to stretch into internal rotation, rather stretch the piriformis and other external rotators and this will make the internal rotation easier. Careful not to strain the knee trying to stretch the hip.

Does stretching the piriformis help both knees touch the floor or only the outer leg?

Actually, MORE the inner leg, meaning the leg going into internal rotation.

That vídeo is pure gold!
