A warm-up is important before physical activity because it helps increase blood flow to the muscles, raises body temperature, and prepares the body for more intense exercise. This can help prevent injuries and improve performance during the activity.

A warm-up routine is important for physical activity because it helps prepare the body for exercise by increasing blood flow to the muscles, raising body temperature, and improving flexibility. This can help prevent injuries and improve performance during the workout.

The treadmill slows down when you step on it because your weight adds resistance to the belt, causing the motor to work harder to keep it moving at the same speed.

The treadmill stops when you step on it because the weight and pressure of your body triggers a safety mechanism that pauses the machine to prevent injury or damage.

The treadmill stops when running because it has a safety feature that automatically stops the belt if the user falls or steps off the machine to prevent accidents or injuries.
