stretch & BC

When stretching why is it so important that the BC muscle is relaxed? Does it realy make a difference?

I think it would be easier to stretch if it is relaxed, but none the less it will twitch after a while,

Pretty sure there is a stretch were you stretch squeeze bc and then relax and stretch further and so on,

Thats all I know:)

Relaxing the bc muscle prevents injury and makes stretching easier to do.

I think it’s probably because the BC muscles surround the crura, which are the “legs” that the corpora cavernosa split into behind the pubic bone. Contracting those muscles shortens the crura. By relaxing them, you’re best able to stretch both the crura and the muscles to get the most extension.
