Which Muscles Make Up the Arms?
There are three main sections of the arm:
- In the Anterior (front) you’ll find the biceps brachii (also known as the biceps), the brachialis muscle, and the coracobrachialis muscle.
- Posterior (back): This portion contains the triceps brachii (or triceps).
- Shoulders: The deltoid muscle sits at the top of the shoulder. And the backside of the shoulder is where you’ll find the rotator cuff, which consists of four small muscles: the supraspinatus, the infraspinatus, the teres minor, and the subscapularis.
Our arms move in all the various ways and we use them in every activity throughout the day, wherein each of the above muscles play their own unique and important role to help them move and complete our action. Any pushing, pulling, reaching, or swinging movement of the arms requires a different set of muscles, and training those muscles can help you carry out different actions with ease, such as carrying a bag of groceries, picking up your baby or holding a plank pose in yoga etc. Increased range of motion can be noticed when you consistently train all the upper body muscles, which can further aid in injury prevention. The muscles in your arm also help support your wrists as well as your elbows and hence strong muscles help in maintaining good joints too. Moreover, stronger arms help avoid increased stress and pressure put on the joints by daily activities like scrolling on your phone or chopping vegetables, typing on your laptop etc.
And therefore, it’s important to make sure to train all of the above three muscles to gain equal strength and well-toned muscles throughout your arm.
