Saw a great video of a dude doing bench press. His story was basically walking into a gym. To the right is a guy of moderate build press an extreme amount of weight. To the left is a guy that is well defined, built, and ripped but he was only doing a light weight. It was then he realized that heavyweight was not synonymous to building muscle. Being a professional body building trainer, his program involves lighter weight, a slow rep to the chest where you hold it for 3 seconds, then push to the top and flex for three seconds then repeat for reps of 8-10. You want to keep your arm pits at a 90 degree, and your arms perpendicular to your torso. I damaged my left shoulder doing too heavy of reps so I have started taking this lighter approach with good results. I was hoping that someday I could return to heavier weight, but I am realizing that I may never go back to the heavy weight...
