Having suffered from neck and shoulder pain for many
years in spite of therapy, yoga and drugs
I stumbled across this odd source of training exercises and philosophy from Elliot Hulse about six months ago
and decided to try the suggestions in the link I've provided here...http://youtu.be/A65Rvivs5g8
The stretches take about 5 to 6 minutes, I use them first thing in the morning and just before going to bed at night.
During long periods of playing, six to eight hours a day these past 5 weeks, I use these simple stretches during my breaks.
The result has been that I no longer have any issues, problems or pain with my neck and shoulders.
I hope this helps anyone else out there who suffers in frustration and pain.
