Interesting observation made by me yesterday, and a few weeks ago that I haven't shared with you guys. I had a few friends over to work on a project, and while they were here, noticed my broomstick with weights on it. They asked me what it was for, so I showed them with a pretty narrow grip (SW + hand on each side) and 10 lbs. I suggested they try it just to see if they could. I suggested the widest grip and to externally rotate your shoulders (just showed them). They went about 112 cm between their hands and still couldn't do it with straight arms (keep in mind this is an unweighted bar).
I would have thought that these teenagers who play sports and are somewhat healthy diet and exercise wise couldn't do this. Like Ido Portal says, if you don't use it, you'll lose it. It is sad to me to see that kids nowadays, no matter how close they are to gymnastics, can't do a dislocate that is extremely wide. Adults I can understand, but not adolescents. Just something to keep in mind. Keep training hard.
