Here are some clips of me reverse band deadlifting. The first is with 635, the second with 685.
I'm pretty pleased with the progress overall, but I need to continue working on the hammies (via the GHR) to get my hips a little lower and get more leg drive. It's hard to tell from these clips if my hips are always that high, or if I'm simply adjusting to how the bands are loading me (e.g. more need for hip extension strength at the top).
