I'm Jeremy Shore for livestrong.com, and this is how to strengthen your scalenes. The scalene muscles play an active role in laterally flexing and rotating the neck, along with elevating the ribs for respiration. For many people, the three pairs of muscles on the sides of the neck called the scalenes are tight due to long periods of sitting with forward head posture. This can lead to headaches, neck and back pain. So, it's important to both stretch and strengthen these muscles. To strengthen and lengthen the scalene muscles, I'm going to show you a great resistance stretch. We're going to start in a seated position with the chest up, abs in, shoulders back or your can perform this in a standing position. I'll take the opposite hand, I'm going to place the back of my hand along my low back to encourage proper posture. From there, I'm going to drop my head to the side, bringing my ear towards the shoulder on the same side. And then, I'm going to take the free hand and add a light resistance by placing it on top of the outside of the head. From there, I want to strengthen this pattern by adding a little bit of resistance, but lifting the head and returning it back to the upright position. And at this position, I'm going to continue lifting the head, but I'm going lengthen by pulling it back with that hand, lightly resisting, tuck into that lengthening position. Then, I'll lift up with the head, strengthening that movement and then I'll stretch as I resist, lightly pulling into that stretch. I'll repeat for six to eight repetitions and then I'll switch sides. I'm Jeremy Shore for livestrong.com, and this has been how to strengthen the scalenes.
