When working out at the gym or following a class in person or online do you hear the instructor refer to muscles you have no idea where they are and what they do or use some words relating to the body that leaves you scratching your head?
To make things a little more clearer whilst you are doing your cardio class or lifting those weights here is a “translation” of some of the more common muscles/words you may come across:
Latissimus Dorsi muscle is a broad, flat muscle in the lower back. It extends the arm, brings the outstretched back towards the body and turns the arm inward. Examples of movements are rowing, swimming and chopping wood.
Rotator Cuff is a group of muscles that surround the shoulder joint, keeping the head of the upper arm bone firmly within the shallow socket of the shoulder. There are 4 muscles and each has its own function with regard to the shoulder including lifting the arm away from the body, turning the shoulder inwards and turning the shoulder outwards. Movements such as playing tennis, brushing your hair or putting your hand in your back pocket involve some or all of these muscles.
The trapezius is a muscle that starts at the base of your neck, goes across your shoulders and extends to the middle of your back. The trapezius helps you move your head, neck, arms, shoulders and body. It also stabilizes your spine and helps with posture. You use your traps in many day-to-day activities such as driving, carrying shopping bags and typing.
Pectoralis are muscles that connect the front of the chest with the bones of the upper arm and shoulder. Everyday movements which involve the pecs are washing dishes, washing your hair, throwing a ball, moving heavy objects.
