When doing The Seal my hips seem to be a long way from the floor compared to those on the video. I have my shoulders protracted and up as high as I can and meanwhile trying to push my hips down into the floor but they're a few inches above the floor and if I position myself so my hips are touching the floor then I can't lock my elbows.
I've been doing the Stretch series for a couple of months now. Is this something that will just come with time or should I be doing something different?
