Global muscles, also known as prime movers or major muscles, are key muscles responsible for generating primary movements and providing the body with strength and power. These muscles are typically larger and situated closer to the body's core. They work in coordination with the stabilising muscles ( they are all your deeper and postural ones- think deep abdominals, diaphragm, rotator cuff of the shoulder, deep gluteal layers of the hip, and the shoulder blade 'pockets') to facilitate various activities.
In the lower body, major global muscles include
- the quadriceps (front of thighs)
- the hamstrings (back of thighs)
- gluteus maximus (buttocks)
- the calf.
These muscles enable actions like walking, running, squatting, and jumping.
In the upper body, major global muscles contribute to pushing, pulling, and lifting movements, and can include:
- the pectoralis major (chest)
- deltoids (shoulders)
- latissimus dorsi (back).
Global muscles play a crucial role in performing everyday tasks and more intense physical activities. Engaging these muscles through exercise helps improve strength, endurance, and overall functional fitness. Proper training and conditioning of global muscles contribute to better posture, balance, and overall physical performance.
