As a strength & conditioning coach, I've received some of the best continuing education by playing around in areas that I don't belong in. Courses geared more towards physical therapists like DNS, the SFMA, and Sahrmann's courses on Movement System Impairment Syndromes have profoundly impacted how I look at coaching and movement. Joe Heiler runs a site called sportsrehabexpert.com, and his annual teleseminar is one of the best resources around for dense and detailed information on the best practices in strength & conditioning and rehab.
