Bench Press Tip - Grip Width
There are 3 main types of grip widths commonly used in the bench press. Close (shoulder width), mid-grip, and a wide-grip (think powerlifting width). Your goal will generally determine the amount of time you spend training each variation. Personally I train with a close grip for the majority of my phases, using a mid-grip secondly as a variation, and then rarely a wide grip. This is because the close grip puts less stress on the shoulder joint then the other two widths and with my history of shoulder and pec injuries it is the grip that allows me to train pain free. I also program this width in a lot for my athletes as I feel it carries over to their sports a lot more than a wide grip does and it also reduces the chance of injuring the shoulder during training.
