Dr. Jacob Goodin is a professor of kinesiology at Point Loma Nazarene University (PLNU), and holds a PhD in Sport Physiology and Performance from East Tennessee State University. He has over a decade of experience as a strength and conditioning coach and sport scientist from the high school to NCAA Division I levels. In addition to his role as a professor and research mentor, Dr. Goodin directs the Athlete Monitoring Initiative at PLNU, which provides testing and monitoring services to over 200 athletes yearly as well as research opportunities for kinesiology students.

The number of likes on this comment is the number of people who just corrected their forward head posture by retracting their scapulae (and extending their thoracic spine aka thoracic reduction)

[CharlieHuter]

I appreciated how you went over every individual muscle and broke it down in a simpler way so anyone could understand.

[isabellefernandez-esej]

I really appreciated the simplicity in the way he explains things because these can be so complex.

[alanaguinaldo]

Thank you for including images of each muscle and where it attaches. This helps visualize where each muscle is located and the action it does.

[larissavenegas]

this video described the 5 main shoulder girdle muscles and each of their respective positions and actions. i really appreciate how dr. goodin explains everything and breaks it down into very manageable chunks of information.

[xaviergamez]

This video was perfect not only for learning the actions of the muscles in the shoulder girdle but also for learning where in our bodies they are. I always love when you include how to strengthen the muscles that we learn about and discuss proper and improper form for the exercises that you mention.

[KatieGonella]

This video went over the muscles of the shoulder girdle and the way they move. I appreciated the detailed explanations Dr. Goodin gave with each of the pictures of the muscles.

[hectorcardenas]

I appreciate the minimalism of the pictures on the slides, the shoulder girdle has so many small muscles and some we may not even cover yet. Despite the trade off of many slides the less the crowded the picture the easier it is for me to demarcate the muscles and better understand their line of action and how that actually translates in things such as upward rotation.

[LaurenSaalberg]

Thanks for including pictures and drawing on them to help explain more in depth. I also appreciate how you grouped the muscles it makes so much sense

[katherine_heekin]

I liked how you individually went over each muscle, highlighting where they are located, and the actions they perform. I was also consciously sitting up straight this whole video with my shoulders retracting.

[shelbyriem]

All of the pictures help explain the actions of the scapula, which is super helpful for such a challenging topic

[EllaLamp]

It is helpful that you give examples of traditional exercises that target each of the muscles. Making those connections makes it easier for me to remember which actions go with which muscles.

[JoeyPagola]

It is so cool to see the functions of each of the shoulder girdle muscles and then to see the anatomy to understand the why behind the action. Each muscle serves a specific purpose and it is quite amazing to understand how these muscles actually work in our bodies all the time.

[ameliabrock]

I appreciate the emphasis on learning through palpation and movement analysis—a hands-on approach really helps my understanding!

[SageFisher-qr]

I definitely became much more aware of my posture thanks to this video! The images and descriptions of each muscle helped me understand the muscle actions.

[isabellecousineau]

My posture is officially fixed thanks to this video!

[rbello_]

I think its been really helpful that you've included a few exercises with each muscle because it helps to kind of visualize each action of the muscles.

[emilyannhively]

It is very helpful how you provided the words on the screen, a visual picture of the muscles/ scapula, plus your own demonstration

[LucasClarkston]

I really like how he went in depth on each different muscle it was really helpful.

[IvyBartlett]

This video was excellent for teaching the locations of the shoulder girdle muscles in our bodies as well as their movements. I always appreciate it when you talk about the right and wrong form for the exercises you provide as well as how to strengthen the muscles we learn about.
