I will try these myself next time - looks like a good exerecise for the posterior chain 
Hammies, glutes, erectors etc
I did not get to see the pic or video clip. Wht do you think of doing them laying on your back and attaching the cable to belt around ankles? (the high pulley). Your feet would be high in the air (vertical) at begining of rep, before pulling downwards away from machine stack.
That does seem like a really useful setup for someone who doesn’t have a reverse hyper machine. The only thing is with that setup is the load decreases throughoout the rep until its at its lowest at the end position which is when the muscles will be strongest. Worth a try though and i might see if i an include a jumpstretch band into the setup to alter the varying resistance.
Gooes2 - that would work, but I’d like to have the leg move beyond the bodyline a bit. And pretty hard to setup and get into position
That’s pretty much what the guy did in the clip, but standing up, single leg.
Acooper, I think if he stood back further from the machine that would be reduced
We do a similar exercise we call kick-backs. The main difference is the starting point, we use the lower pully and start with a bent knee (A-march position) and straighten the leg so the knee is fully extended as it passes under the body. The hip continues to extend behind the body to a point just before the hip begins to rotate.
