Working together though, the abductors and adductors can be used to stabilize you when you are in compromising positions such as being on one leg.
Being such small muscle groups and the lack of knowledge on how to properly work them, the abductors, and more often the adductors can be easily injured. Mostly during sports such as soccer, football or hockey, players who “pull their groin” have actually strained their (most likely under developed) adductor muscles.
The best way to avoid these types of injuries is to know how to properly train both your abductors and adductors. Because like your hamstrings and quads, or your chest and back, or your biceps and triceps, you need to work out these muscles equally to prevent an imbalance which can lead to injury.
