9 Change your grip on barbell benches
Rather than taking a standard grip on a barbell, consider repositioning your hands, ranging from very close to very wide. With your hands fairly close together, your inner pecs get worked to a greater degree, the range of motion is the longest, and your triceps are heavily called into play. Pushing your hands way out, on the other hand, moves the target to the outer portion of the pecs as well as the shoulders, while the range of motion is highly restricted.
I’m not suggesting you use either extreme: I’m just pointing out that there are a number of hand positions slightly different from what you’re probably doing now. Each position recruits the musculature in a slightly different way. Consider occasionally working with a slightly closer or wider grip on the bar. It’s a great way to boost your overall chest development.
