To reap the benefits of exercise for your problem-solving skills, you need to choose the right type, intensity, and duration of physical activity. According to research, aerobic exercise, such as running, cycling, or swimming, is more effective than anaerobic exercise, such as weight lifting or sprinting, for enhancing cognitive functions. Aerobic exercise increases the blood flow and oxygen delivery to your brain, which supports its health and performance. You also need to exercise at a moderate to high intensity, which means that you should feel your heart rate and breathing increase, but not to the point of exhaustion or discomfort. Finally, you need to exercise regularly and consistently, preferably at least three times a week for 30 minutes or more.
