Improving mental acuity with cardio workouts also helps with mood and aerobic capacity. Whether its daily walks around the neighborhood or regular workouts on an elliptical or rowing machine, this consistent and sustained exercise will enhance your body's ability to metabolize fats and carbohydrates into fuel. It will make walking to get the mail, lifting yourself out of a wheelchair or running a 5K that much easier and more doable! If you set reasonable goals for your activity it will be easier to mark your progress and see advancement, and therefore feel more empowered and competent. By continuously meeting these graduated goals you will be able to expand your level of activity and improve your mental outlook. Simply adding cuff weights to your normal tasks will allow you to see the fruits of your labor and clear your mind for more complicated endeavors like a recalling directions or an appointment, perhaps even purchasing plane tickets for that long awaited trip? In my most frustrating moments I have stopped, walked around the block and returned with not only vigor for the task but several added ideas to improve the outcome. By allowing more oxygen in you will feel stronger and feed each and every cell in your brain and body. Try to make that walk to the door or around the block in order to feel the benefits for yourself and there will be no limit to your achievements big or small!
