We all know that logging miles on the treadmill can help with weight loss, but adding more cardio to your life will also boost your productivity, rev your energy, and turn you into an unstoppable success machine. Even one 30-minute cardio session pumps extra blood to your brain, delivering the oxygen and nutrients it needs to perform at max efficiency. Cardio also floods the brain with chemicals that enhance functions such as memory, problem solving, and decision making.
