I kinda wondered about that too Irish!!! Thats just like the gym i trained at in the 80's!!!! I trained at suncoast gym in tampa, rick weil trained there, well he would do reverse grip benches as a assistant exercise...I came home from college, and did these just to do them...well, by monday, the whole gym was doing them..A guy I trained with then, he was a super heavy weight, world champion at that time, and a crazy bastard, came up with the idea to make up exercises, and see if everyone would do them! So, the next day, he stood there, facing the mirror, with a 100# db, raised it out straight in front of him and would bring it in and touch his nose! We yelled, "come on, get one more! Push it!"
then he says, man, those are great for your bench!!! LOL Low and behold, every goober was doing these by monday!!!!! LOL
