What do you guys think of the "Power Runner?"

Take a look: http://www.powerrunner.com/

Is this the reverse leg press exercise Charlie advocates?

Hey Charlie,

What do you think of this contraption? I’m very skeptical of most things, but this machine looks
decent for reverse leg presses.

You can do the same exercise on the horizontal leg press.

it swings too much. There’s one in the gym I use and no one uses it.
