does rock climbing make your hands bigger?

As a climber, I can tell you that rock climbing itself doesn't necessarily make your hands bigger in terms of bone structure. However, consistent climbing can lead to increased muscle development in your hands and forearms, which can give the appearance of larger hands.

The repetitive gripping and pulling motions involved in climbing can strengthen the muscles in your hands and forearms, making them more defined and potentially bulkier. This can give the impression of larger hands, particularly in terms of muscle size.
