Trainer Dana Sorensen explains how our bodies compensate for weaknesses by taking the path of least resistance, which often leads to injury.
In softball, perhaps the best example of this is when a young pitcher starts having shoulder pain from throwing. This means that somewhere during their training process, their body encountered weakness and instead of strengthening that weakness, they resorted to compensating with improper movements that resulted in injury.
It's critical to proactively train the shoulders to properly move through a series of programmed exercises and band exercises: This includes rotator cuff exercises and shoulder mobility exercises. Take time to do a focused and careful shoulder warm-up prior to practice and then recover after practice.
