You can also rotate your hand and then push down on your top knuckles, if you’d like to catch any knuckles you missed with the first squeeze. You can also just concentrate the pressure on 1-2 fingers. This way, you’ll only crack the section of knuckles where you want relief.
You’ll see this one in movies whenever some muscular goon is about to lay some whoop down. We don’t know the origin of the trope, but it’s probably the “coolest” way to crack your knuckles!
The bottom knuckles should be easiest to crack, but the top knuckles can crack, too.
Repeat this process on any of your other fingers to crack them as needed.
And even fewer people can crack the same finger immediately after they have already popped it. This may not be the case for you, but if you’re having problems, consider waiting 5-10 minutes and crack again.
If you only crack your knuckles every now and then, you’re probably going be fine.
