Squeeze your pinkies!
This simple detail is great for improving your bench press.
Proper alignment between the bar, your wrists, and elbows is crucial for a big bench press. Benching with your wrist bent back is not only inefficient, but can lead to wrist pain.
Setup with the bar tight into your thumb, deep in your palm (not your knuckles) and SQUEEZE!
Give extra attention to squeezing your pinkies and you will notice increased tightness. This extra tension will help keep your wrists from extending back and keep the bar in proper alignment. Better alignment allows for a better transfer of force. By crushing the bar as tight as possible you signal the nervous system to involve more muscles. Tighten your grip and the weight will feel lighter in your hands.
