Don't you hate it when your training seems to be going great and boom; it hits you, chills, fever, achy joints, runny nose, cough etc. As diligent as you are with your diet and taking your vitamins you come down with the flu and get sick.

The best thing to do is to bite the bullet and get plenty of rest. Depending on the severity of your illness, either cut back on your training, or take time off from the gym all together until you feel better. Double the dosages of Vitamin C & E to flood your body with powerful antioxidants to help fight off the virus. Also make sure to drink plenty of fluids. It is also important to continue taking your whey protein and glutamine supplements as these contain glutathione, the central component of cellular immune defense.

As there is no cure for the common cold, the best advice is preventing getting sick in the first place. Here are some tips to keep your immune system strong and healthy.

Wash your hands frequently- and keep your hands away from your eyes and mouth. The flu virus is easily picked up by physical contact from doorknobs, money etc.

Get adequate sleep- studies show sleep deprivation plays havoc on your immune system. If you're training hard in the gym you need proper rest.

Avoid crash diets- drastically reducing your daily caloric intake robs your body of the nutrients it need for optimal metabolic functions.

Increase Vitamin C & E intake- these powerful antioxidants work synergistically to boost your immune system.

Don't overtrain- training too long, too often suppresses immune function. In the hours following an intense workout your immune system is lowered making this the most susceptible time to catch the flu bug. Supplement directly after your workout with vitamins, whey protein, insulin spiking carbs and glutamine.

Supplement with whey protein and glutamine- as mentioned above these are your bodies building blocks for a strong immune system and cell growth and repair.
