I just started doing extensions again after a long hiatus from them and remembered this basic technique. It definitely provides a pump superior to conventional extensions and seems to work the upper 1/3 of the quad more effectively.
Very simple technique. Complete a full range rep, squeeze hard in the top postion for a count with toes pointed straight at the ceiling, lower only about a quarter of the way down, then return to the top. That's one rep.
