Aaron Marino of alpha m. addresses the risk versus benefit with heavy weight and low reps to pack on size. The best way to get hurt is lifting heavy weight with low reps. A lot of strain and pressure is put on your tendons.
Aaron recommends 6 -12 reps. If you get to 12, perhaps it’s too light and up the weight. The muscles and body gets a better workout from the range of motion and adequate weight that tears down the muscle tissue. Use a weight that is challenging but not risky.
It’s not how strong you are; it’s about how strong you look. No one cares about how much you lift. Be safe and use your head … and your biceps.
