Do you use social media to communicate with your clients?

My personal training company use social media to keep our clients up to date with anything new in health and fitness . We post news, workouts motivational quotes and nutrition information almost daily to our Tumblr blog (www. fitnessfirstaz.tmblr.com) which auto posts a link to our Facebook page and Twitter (not our personal pages but our company pages). Social media helps you reach not only your clients but thousands of people who may have never known about you. With more and more people turning to the internet for information as trainers (no matter how impersonal you may think it may be) we have to stay relevant. It also allows you to reach more people and network with other trainers and companies that may be able to help.
