Sadie Marquardt thank you, as always, you're videos are so good at explaining how the pieces of the moves fit together. 

Would u say that the lower undulation mechanics is the same or similar feel to the lower pelvic posterior and anterior tilt (like in this video - Introduction to Pelvic Isolations and Rolls?)

Hey Anna, sorry if it missed in the video but what weights are using? 

Sadie Marquardt thank you quick reply and advice! I will try the block technique 😀

Hi, to help keep my legs being involved would you recommend squeezing the glutes?
