Explanation:

At the start of exercising or when performing tasks, your muscles feel strong and resilient. However, over time and after repeating movements, your muscles may begin to feel weaker and tired. This can be defined as muscle fatigue.

Muscle fatigue is a symptom that decreases your muscles’ ability to perform over time. It can be associated with a state of exhaustion, often following strenuous activity or exercise. When you experience fatigue, the force behind your muscles’ movements decrease, causing you to feel weaker.

While exercise is a common cause of muscle fatigue, this symptom can be the result of other health conditions, too.
