Hey Coach, that last exercise is for shoulders? Is it a barbell that you place in a corner and load one end and press with that end? I may give this a try if that is indeed what it is.
Grape Ape is correct, it's a landmine press. We do them for a variety of reasons. In Gilles case, it was because he had injuries while preparing for Dancing with the Stars, including shoulder and a hamstring tear. We use this in place of an overhead movement to build strength and stability without the risk of a direct overhead press. Shoulder/scap stability, rotational core, and hip explosiveness.
