I read on the internet that it is important to keep your elbows 45 degrees to your torso. I usually perform my bench with about an 80 degree elbow position to my torso. I tried doing the 45, it seemed like I couldn't lift as much weights as before. And wouldn't it be considered a close-grip bench if you did a 45 degree elbow position as you would have to bring your hands closer together? I want to know what you guys think about which is more beneficial. Thanks!
