Question

Doing a warmup before exercise is important because it?

Answer 1

It stretches out and warms up your muscles so you don't pull them, causing injury.

Answer 2

The warm-up should gently prepare the body for exercises by gradually increasing the heart rate and circulation; this will loosen the joints and increase blood flow to the muscles. Stretching the muscles prepares them for physical activity and prevents injuries.
