Try exercising to reduce your overall cholesterol levels. Diet is enough to get them down to healthy levels, but you can get better and quicker results if you add exercising to your regimen. Generally, people who exercise have higher levels of HDL, or good cholesterol and lower levels of LDL, or bad cholesterol, than those who only eat a healthier diet.
An important fitness tip is to never exercise when you are sick. When you fall ill, your body needs all of its available resources for healing and recovering. Working out when sick will do more harm than good. So you have to have a break from working out until you feel better. To speed your recovery, eat properly and get sufficient sleep at night.
