Reverse grip benches are used to place emphasis on the triceps. Some PL types use them as assistance. On PL type, Anthony Clark, actually used them in competition, with a wide grip, however, most people use them with a grip just slightly wider than shoulder width, to place emphasis on the triceps plus to take strain off the wrists. Here is how I do them. I slide my bench through the racks, so that I don't have to move the bar over my face when unracking.With a grip slightly wider than shoulder width, and a reverse grip, my elbows aare pretty close to being in line with my body. I l;ower the bar in a natural arc, and the bar touches me right around the sternum, then push up in the same arc. The bottom position might vary, due to bone length, etc, but this is what works for me and others, and keeps strain off the wrists.
