One of the first things I thought of when I saw the design of the [words=http://www.mattersofsize.com/forum/showthread.php?83577-Length-master-official-order-thread-now-shipping-06-16-2014!!!]Length Master[/words] with its bundle attachment and arms was if it was possible to use your feet with it in some way, because the footlong stretch can be powerful and you can push harder with your feet with less effort and strain, but gripping with that stretch has always been tough.
Once I got the [words=http://www.mattersofsize.com/forum/showthread.php?83577-Length-master-official-order-thread-now-shipping-06-16-2014!!!]Length Master[/words], I tried to get my feet behind the handles but I couldn't... then I saw the rope and figured out how to incorporate that into a [words=http://www.mattersofsize.com/forum/showthread.php?83577-Length-master-official-order-thread-now-shipping-06-16-2014!!!]Length Master[/words] Footlong stretch.
Because you are using both your feet (which can more comfortably use more pressure) and hands together, bundled, this stretch is very intense.
Make sure you wrap properly, with the wrap starting 1 inch behind the head, and attach the bundle attachment a quarter inch behind the edge of the wrap. I use Theraband alone as wrap, cut 3" x 15" bought from Bib. Wrap should be somewhat loose and not restrict bloodflow, as in this example: http://mattersofsize.com/forum/showthread.php?t=17715
You may be able to use the bundle attachment without wrap, I don't know, but when I try it tends to pinch the skin while the wrap gathers the skin all in one location so it cannot pinch. The wrap really helps protect the skin in more ways that that, too.
Here is the exercise:
1. Wrap, then get in the bundle attachment, with the adjustment screws on top of the device and the arms of the device arched away from you.
2. Turn the handles to get in bundled mode. I can only turn it 1 1/2 times comfortably, so I only turn it 1 time.
3. Sit back in a chair (preferably one you can lean back or slouch in comfortably).
4. Put the rope attached to the [words=http://www.mattersofsize.com/forum/showthread.php?83577-Length-master-official-order-thread-now-shipping-06-16-2014!!!]Length Master[/words] under your feet. I find it helps to put the rope in the space between my pinky toe to keep it locked in place.
5. Lean back and push with your feet. You can also push the arms of the [words=http://www.mattersofsize.com/forum/showthread.php?83577-Length-master-official-order-thread-now-shipping-06-16-2014!!!]Length Master[/words] or grab the circle area of it and push for an extra push.
From here, if you move your feet further apart from each other or slouch/lean back more, you can use more pressure, and if you pivot your hips you can hit different angles.
An alternate way to do this exercise, or perhaps a second exercise is, while in this state put the rope over your knees. The rope should lock in place between the bones of your knee (on the inner space between the kneecap and the bone).
In this state, you can bend your knees in and out, pivot your hips, lean back more or less, or grab the arms/circle and push to hit different angles or add pressure. This second method is more intense, but both methods hit different angles.
Another way to do this may be to go from the original stance and put the [words=http://www.mattersofsize.com/forum/showthread.php?83577-Length-master-official-order-thread-now-shipping-06-16-2014!!!]Length Master[/words] under your legs. I found this to also be intense, but it takes more skin to do this than I have, so I can't do it well just yet.
