Can genetics affect deadlift strength?

Yes, genetics can significantly affect deadlift strength. In a discussion with Tim Ferriss, Dr. Stefi Cohen emphasized that factors like body proportions and muscle fiber composition, which are highly influenced by genetics, play a crucial role in deadlift performance. For instance, someone with a short torso and long arms might find deadlifting more mechanically efficient due to their leverages. Such genetic advantages can allow some individuals to lift significantly higher weights more easily compared to those without these traits, even if they train equally hard 1.

Dr. Cohen also stressed that while hard work and proper training are essential, some physical attributes crucial for powerlifting success cannot be replicated or improved through training alone. These attributes enable certain individuals to excel exceptionally in powerlifting due to their genetic makeup 2.
