Are Big Forearms Genetic

Why do some people have huge forearms?

But they’re normal based on the reality that they grow from strength training like any other muscle group. What is this? Therefore, the main reason why you might wind up with forearms bigger than biceps is that you’re simply training your lower arms harder and heavier than your upper arms.

Are small forearms genetics?

Also, it’s possible that your skinny forearms are due to your genetics. If you’re somewhat tall or simply have less overall muscle, then your body mass will naturally be distributed over a larger surface area, which can result in your lower arms looking a little thin.
