The objective of the study was to create a training program for deep cervical muscles and help physical activity and sports professionals when exercising them. There are very few guidelines related to exercising these muscles, but at the same time, scientific literature demonstrates its close connection with neck pain. Therefore, previous research is used in order to develop a training program focused on deep cervical muscles, as well as its corresponding evaluation methods, including a new cervical extensor test aimed at achieving a more accurate estimation of strength and resistance. Finally, a case study is presented; a woman not suffering from neck pain but having associated risk factors, who follows the program as a means of preventing it, showing clear progress after its completion.
