We have two filmed exercises: sitting 90/90 and prone press-up. There is no third filmed body. This page is the written lateral / side-glide experiment. Jessica is talent, not the brand.
After both filmed directions, if symptoms did not move toward the back and did not spread farther down the leg, some people try a side-to-side shift. That is not a third silent MP4 and not a named clinic method.
Stand with feet about hip-width. Keep the shoulders quiet. Shift the hips a little to one side, then return. About 10 repetitions on the easier side, then reassess. Stop the same session if pain or pins-and-needles spread farther down the leg, or if new saddle, bladder, bowel, or sexual-function change appears — seek care, not more reps.
The two filmed files stay the filmed files:
