The standing lateral raise primarily works the shoulders.
Muscular dystrophy (MD) is a group of genetic disorders that cause progressive weakness and loss of muscle mass. It primarily affects skeletal muscles, which are responsible for movement and posture. MD is caused by mutations in genes that encode for muscle proteins, leading to abnormalities in muscle structure and function. The severity and progression of MD can vary depending on the specific type and the age of onset.
Muscular dystrophy is a group of inherited disorders that involve muscle weakness and loss of muscle tissue, which get worse over time.
The standing lateral raise primarily works the shoulder muscles.
Basically muscular endurance is how many times you can use a muscle group before it tires out. Ex. when running the distance you can go before you're llegs tire.
