Abductor Muscles are the muscles that move a limb away from the midline of the body to the side. The most notable abductors run on the outside of the shoulders and the outside of the hips and thighs.
Stretching too far can cause abductor strain in the shoulder or hip. Symptoms include localized pain and swelling when you raise your shoulder or hip, depending upon the location of the injury. There may also be muscle spasms and difficulty contracting the muscles involved.
A great way to strengthen the abductors and prevent injury is through exercise, with or without, resistance bands. The exercise shown in the above video is quick, simple and if done every day will keep your abductors toned and strong. Two or three sets of 12 reps each is a great way to get started. Even if done without the resistance band this is a very effective exercise.
