For the past 30 days one of the world's best coaches, Eric Cressey, has been posting a quick 1-3 minute video on arm and shoulder health. In these 30 quickfire practical tips you will learn how to assess arm and shoulder health, exercises, cues to improve mobility, and more. I loved this series from Eric and hope that you do too.
