Weird popping when coming down after a curl?

[Atty]

Lately when I do two handed bar curls I get an odd popping in my shoulder. After I come down from curling, as my arms are going down straight, I get a weird pop in both shoulders, its like a huge knuckle cracking, it doesn't hurt, it actually feels kinda cool in a weird way, but I don't know if I should be concerned about it.

It started a few days after I started working on my posture, I used to walk with my shoulders down and would almost slouch a bit, but I've been working on not doing that, and ever since I've been having this pop, so I think thats the cause, but still, I'd like to know what it is and if I should be worried.

How's your form?

I asked a few people what they think, friends and random people, even a trainer at the gym, and they all said it was good.

Weird, but not uncommon. I get pops and cracks all over. Just be careful to make sure that no pain is being caused.

stop doing em for a while. i've had random pops that occur and ones that randomly go away just need to try other things if it bothers you
