Having great flexible shoulders can make your day to day life much easier and improve your posture, as well as your gymnastics!
Basically, can you make you hands meet behind your back? If so, you are well on the way to some really useful shoulders, if not, this is your first port of call. Develop your shoulders individually, both the reaching down and the stretching up parts.
Work on these sub-stretches, with some other drills we will show you, and your shoulders, too, will become lovely.
