Which way do you put lemon in squeezer?

Excuse me, could you clarify for me the proper way to insert a lemon into a squeezer? I've noticed that some people do it one way and others another, and I'm curious about the most efficient or commonly accepted method. Is there a specific technique or position that is recommended to ensure the most juice is extracted from the lemon? Also, do you have any tips or tricks for getting the most out of the process? Thank you in advance for your assistance.
