Does the sternocleidomastoid (SCM) muscle cause a pull, and tingling sensation in my thighs and legs? I get this pull and tingling sensation in my thighs and legs when I lower my head toward my chest only. Why is that?
Sincerely,

There are two muscles that are in your chest. These two muscles are known as the pectorals major and the pectorals minor.
Pectorals
Diaphragm
The large medial area of the chest is called the sternum. It is a flat bone located in the center of the chest, and serves as an attachment point for ribs and some chest muscles.
Everyone has muscles on their chest. Those muscles are there to help you breathe. They help your chest expand and contract when you breathe. If you are an athlete or an opera singer, you need all the air in your lungs you can get. In your training, you develop chest muscles. The fat lady in the opera, is not all fat. She has tremendous chest muscles because she has developed her lung capacity. She can hold a note and go without breathing much longer than an average person.
Yes, planks can effectively work the chest muscles as they engage the core muscles which support the body in a plank position, indirectly working the chest muscles as well.
The intercostal muscles are the muscles that lie between the ribs and form the chest wall. Their function is to aid inhalation and exhalation.
To flex your chest, you tighten the muscles that are in that area. This might include your arms or back as well, but you tighten the muscles in your chest and abs.
Planks are not very effective for building chest muscles. They primarily target the core muscles, such as the abdominals and lower back. To build chest muscles, it is better to focus on exercises like push-ups, bench presses, and chest flys.
No, skull crushers primarily target and work the triceps muscles, not the chest muscles.
The muscles under the ribs in the human body help with breathing by expanding and contracting the chest cavity to allow air to enter and exit the lungs.
