What causes strains?

* Muscle overload: This occurs when a muscle is forced to work beyond its capacity. It can happen suddenly, such as when you lift a heavy object, or it can develop over time, such as when you overuse a muscle in your daily activities.

* Insufficient warm-up: When you don't warm up before exercising, your muscles are not as flexible and are more likely to tear.

* Muscle fatigue: Muscles that are fatigued are more likely to strain. This is why it's important to take breaks during exercise and to avoid overtraining.

* Age: As you get older, your muscles lose strength and flexibility, making them more susceptible to strains.

* Certain medical conditions: Some medical conditions, such as diabetes and obesity, can increase your risk of developing strains.
