I had a shoulder impingement a few years ago as I started climbing. Solution to the problem has been climbing with an active shoulder and also exercises from the book Climb Injury-Free. In general I can recommend this book to everybody with smaller climbing related injuries. That's why I send every climber friend a few hints and exercises from the book if they have for example a tennis or golfer elbow. Since approximately two month I have a tennis elbow or lateral epicondylosis. So today I have decided to build myself a wrist roller or dowel constrcution.
