While bone growth in the hands typically ceases after puberty, muscle development and strength are not limited by age. Can you increase the size of your hands? The answer depends on understanding the difference between unchangeable genetics and trainable physiological factors.

Studies consistently show that your inherent bone structure is determined by genetics, and this includes your wrist size. So, while you cannot alter your skeletal frame, can you control wrist size by changing the muscle and tissue around the joint? We break down the science behind this common question.

Studies have shown that genetic factors can account for as much as 85-95% of the variation in limb muscle circumference among adolescents, indicating a significant hereditary influence. However, the answer to the question, 'Is forearm size genetic?', is not a simple yes or no, as environmental factors like consistent training also play a crucial role.
