swivel hips and skiers form check

i've attached 2 different videos of me doing swivel hips.  i notice that the description of F1 actually says to keep the glutes on the ground, but the athlete demonstrating the move actually has his glutes come up off the ground a little bit.  

 

swivel hips version 1.  my glutes are coming off the ground a little bit

swivel hips version 2.  i'm trying really hard to keep my glutes on the ground.  unfortunately, i just realized that the angle of the video sucks, and you can't see my knees:

i don't need to do these perfectly.  i just want to know if they are good enough to move on to the next progression.

 

thanks for any responses

hips looks good.

 

don't need to hurry so much.

 

skiers needs to be knees together.

great, i'm glad that the swivel hips look good!  which swivel hip version was best - version 1 or 2?

 

i'll work on the skiers.  i think i want to get a little bit more ROM on them anyway.

 

thanks
