If you should eat right for your blood type, should you work out accordingly as well? Of course you should. If you believe that your unique DNA footprint and genetic makeup is predisposed to specific foods, then won’t your physical fitness needs differ according to your blood type as well?

In other words, should you exercise in a way that is consistent with the physical activity your blood type ancestors enjoyed on a daily basis? That is the premise behind exercising according to your blood type.

Type O – The Hunter

The human ancestors which first appeared with blood type O, the oldest of the 4 current blood types, was a Hunter. The day was spent hunting down and killing animals for food. When your type O predecessors weren’t chasing animals, animals were chasing them. This means they were constantly on the go, and your workout routine should reflect that.

Type Os tend to be more athletic, stronger and more powerful, than other blood types. However, there is a problem with your natural tendency as it relates to your modern lifestyle. You are probably not chasing down food or being chased by hungry predators anymore. This means you could have packed on some extra weight due to a sedentary lifestyle.

All you have to do is replicate the daily habits of your on the go ancestors and you can reach and maintain a healthy body weight. The original type O’s enjoyed extremely intense bursts of physical exertion, followed by periods of rest. This is why you should tend towards high intensity interval training (HIIT), plyometrics, running and other types of interval training.

Just as your caveman ancestors got an emotional response when they took down some big game animal, you use exercise as an emotional outlet as well. Physical fitness and physical activity are the best tools for you to fight stress and anxiety while also boosting your mood and mental well-being.

Think about it. You are a type O cave dweller who hasn’t had any fresh meat in days. You have subsisted on water and what plant-based foods, nuts and berries you could scavenge. Then out of nowhere a heard of gazelles wonders past.

If you and your fellow cavemen can just take down a few gazelles, you can enjoy plenty of the fresh meat your body loves. Your mind and emotions soar at the thought, and that same anxiety-busting, stress-defeating feeling is yours anytime you enjoy some intense exercise.
