In December of 2012 I tore my right adductor in a meet. I had actually had some minor tearing early in the year and had been managing it to keep training but with a 782 competition squat it let go on me. https://youtu.be/YoEJMEFJAYI
After rehabbing the area I determined a need to reduce my injury risk. With squatting wide and pulling sumo it simply puts a lot of strain on this area that is sometimes slow to recover. It is also a fairly common injury point with lifters.
