BECAUSE OF THIS STRUCTURAL ABNORMALITY, CERTAIN LOWER EXTREMITY EXERCISES MAY PERPETUATE SYMPTOMS OF FAI AS A RESULT OF POSITIONING. THE PURPOSE OF THIS ARTICLE IS TO PROVIDE INSIGHT INTO THE STRUCTURAL PATHOLOGY AND PROVOCATING FACTORS ASSOCIATED WITH FAI. PRACTICAL EXERCISE-BASED MODIFICATIONS SPECIFIC TO FAI ARE PRESENTED IN AN EFFORT TO MITIGATE THE IMPAIRMENT SEQUELA AND PROMOTE PAIN-FREE TRAINING.
