How do shot putters decide on the weight of their shot?

I know the weight is standardized for competition, but I’m wondering if athletes practice with different weights or have preferences for training. Do heavier or lighter shots help develop different strengths? Any tips from experienced throwers?

Shot putters choose the weight of their shot based on their size, strength, and technique. Heavier shots can go further, but they're also harder to control.
