Blood type A appeared when human beings were first learning an agrarian way of life. No longer did human beings have to subsist on food that they hunted and caught. This made life easier and more predictable, less stressful, and improved how long human beings lived.
These humans learned to farm, and slowly adopted a diet which was more heavily plant-based than meat-based. Over time their digestive systems changed as well, to accommodate this nutrition-based change.
You can only eat meat when it is available, so when there were not herds of animals around, your hunting ancestors went hungry. Ancient man often times over-hunted animal species until there were very few animal-based food sources around.
When man smartly learned to mimic nature and grow his own plant-based foods, he could plant seasonal crops all year long and never have to go hungry again. With this substantial change in nutrition came blood type A, as well as a totally different daily lifestyle.
Type A – The Farmer
Farmers many times get up and go to sleep with the sun. They are active all day long. In many cases, your ancient farmer ancestors were a lot more active on a regular basis than their hunting, type O predecessors. If you have blood type A, your genetic makeup resembles that of the first farmers in human history.
You may have a tendency to get up early and stay up late, a trait you owe to your ancestors. Your exercise needs should also mimic the physical activities of those long-ago farmers. They spent their days performing slower paced, less intensive activities like planting and harvesting crops, rather than performing short bursts of intense physical activity which was required for type O hunters.
This is why you should try to avoid intense exercises that increase your levels of the stress hormone cortisol. This can lead to muscle fatigue and stiffness, which causes stress rather than alleviating it. Think about how a farmer used to spend his day, performing longer duration physical activities that were less intensive.
To mimic this process, focus on practices which are slower paced and help protect your joints, like tai chi, yoga, Pilates and even isometric exercises and meditation. When dealing with stress, these mentally calming activities can soothe your mind and quiet your nerves.
For both stress relief and physical fitness, less intense, longer duration exercises and physical practices are recommended for type A’s.
