Twitter

I have just recently discovered how beneficial Twitter can be professionally. I have stumbled upon a great community of physical educators who post great content in regards to activities, procedures, evaluations, etc. It's been the best professional development I have encountered.

It's also a great resource to put information/reminders out to students and parents.

I have found it to be beneficial for coaching golf.  The information about golf from teaching techniques to practice ideas is outstanding.  I am sure it is the same for any sport.
