Yet another variation on the back extension, this time with a row. You could do this with a barbell, but I prefer kettlebells as this gets heavier, mainly because I like each side to be working independently. It also doesn’t hurt that the KBs are easier for my short arms to reach from the top of the reverse hyper. You certainly don’t need any special equipment for this except a friend who is willing to potentially get kicked in the face (my sweet coach is a brave, brave man as you can see here) and something upon which to elevate yourself. My coach found this variation in an old video from the 80’s (complete with mullet and mustache) of a wicked strong French shot putter.
