• Heart: Your heart is a muscle and responds positively to endurance exercise. A strong and effective heart pumps blood more effectively not only when you exercise. Heart specialists say that this “fit” heart is more resistant to heart disease.
  • Lungs: On our long runs, our lungs are stimulated to improve oxygen absorption, loading up the red blood cells for continuous delivery of oxygen to exercising muscles.
  • Endorphins:  They kill pain, make you feel good. Endorphins manage muscle pain and provide a positive lift to the spirit. This is why you feel good after a workout. Through managing your effort you can enjoy the benefits during exercise.
