I saw a video with a guy getting a broom stick and holding it in front of him then snapping it behind his back to stretch his shoulders... It looks painful... Kinda scared to try that
You dont snap it bro...just rotate nice and easy. That is a great stretch/strengthening tool. BUT....just use a fitness band not a broom stick. The fitness band will allow your shoulders to move as they need to with added resistance pulling them apart. Wont be so akward. Blue or black fitness band is fine.
