Don’t use a “thumbless” or “suicide” grip (as its aptly called), which has your thumbs next to your index fingers as opposed to wrapped around the bar. While people give various reasons for liking the thumbless grip, its disadvantage is obvious: when you’re going heavy, it’s surprisingly easy for the barbell to slip out of your hands and crash down on your chest, or worse, your neck (just Google “thumbless grip bench press accident” if you don’t believe me!). Put the bar in the palm of your hand, not in your fingers, because this leads to wrist pains.
