I've heard this can be cracked. What is it and how is this performed?
I believe it is the upper part of your breatbone - dont know how you'd crack that to be honest. its the only part of me (besides knees) that dont pop
I try and hold the left side of my body stationary, then twist my right arm around towards the rear. Usually opens up whatever joint is in the chest. Seems like there's a lot of confusion about exactly what joint this is?
yes i dont have a clue what it is, can u explain please
i can do this or should i say it sometimes cracks,it realy only does it when it feels like it.
