Now that some of the crisis surrounding my symphony employment has been averted, it's time to get back to movement teaching, writing, practicing, and more, although I will write a little about that San Antonio Symphony situation. For now though, here's an easy shoulder warm-up, in a few different ways.
1) Try externally and internally rotating your arm bones without weight first. You can see here that my floor is a little uneven, so one side of my body is up a little higher than the other.
2) Add a small weight, maybe 2-3 pounds.
3) No weights? Try yoga blocks, which can be good, especially if they're cork or wood.
4) No weights or yoga blocks? Try books- Harry Potter books 5-7 are an excellent weight!
