Lying Leg Extension-NEW INVENTION

I spoke of doing lying leg extenions some years ago. I was hoping some company would "get it" but it never happened. SO, I design and built my own. I think it's the first one ever made. I know some old time authors like Vince Geranda talked about doing them , but they never really said why. This short video was done in the gym the night I rolled the machine out on the floor. More to come . You can see the old video on this playlist.
