@04:20 - looks like some kind of special technique, he says in the video that's how you would get the most amount of stimulus on your triceps
Nice way to get a nasty cut from a lightly frayed cable. I think markus ruhl did them like that must be a german thing.
The special technique part is bullshit. That's just how you end up doing pushdowns if you've gone way too heavy with the weight stack. At best that movement is just an okay substitute for close grip bench.
That guy looks like shit. HTH
