You can do this protocol using a neutral, wide, or underhand grip. I like to use a different grip each time to create a different stimulus. The isometric is performed at the bottom position because this is the point of the ROM where most people cheat.
You may know the name of a particular exercise, but do you know what the agonists in the movement are? How about the synergists? Hrrummpph! And you call yourself a weightlifter!
