These are the same as "fat man rows" except the grip is taxed to a much greater degree.
We perform these on a regular basis because the mid back is so weak on so many athletes AND this position allows for many variations to either increase / decrease difficulty for the athlete.

For decrease, have the athlete pull feet in so legs are at a 90 degree angle and hips are parallel to ground, no hip sagging.

Fir increase in dfficulty, the athlete can explode upward so that the rope loosens at the top and on the way down the extra velocity hits your grip hard and you must hold on extremely tightly.

This is what I call a "plyo pull"
