Warm-up pre-run is so often overlooked. A good warm-up before a workout dilates your blood vessels, ensuring that your muscles are well supplied with oxygen.

After physical activity, your heart is still beating faster than normal, your body temperature is higher and your blood vessels are dilated. This means if you stop too fast, you could pass out or feel sick.
