How do I do chin tucks

[Recessed Bateman]

Someone knows a post or a tutorial on how to do chin tucks properly and how much do I need to do?

Try to make as many double chins as possible, while your back is against a wall

Do it as many times as you can

Like this post if you find it helpful and put it as solution (it's the check mark on my right)
