(23)Engaging in regular exercise improves your overall health, mobility and stamina. It leads to much better consumption of vitamins, minerals, other nutrient substances as well as oxygen in your body. However, in spite of your best efforts, you will eventually miss a workout. If consistent exercise is so beneficial for your health, what happens when you skip a few sessions, take a protracted workout cessation, or when you just stop exercising?
   Shortly after you begin discontinuing your normal exercise sequence, noticeable changes begin to occur in your body based upon your level of fitness. Your cardiovascular health, muscular structure, brain function, emotions and concentration can be impacted. You develop an elevated risk for chronic illness.
   Dr. Harry Pino, personal trainer and rehabilitation specialist, exercise physiologist, consultant and experienced marathoner, is quoted heavily by many on the subject of detraining. (24) In this article, Dr. Pino states that "It’s shocking to see what happens to the body. We start to see lots of changes to muscle, strength, and fat levels—it really deteriorates your structural well-being. The fitter you are, the harder you fall." The better conditioned you are, the faster you lose your well-earned fitness position.
   Fitness levels for athletic people decline at varying rates based upon whether strength or cardiovascular losses are at risk. According to Andreas Bergdahl, Assistant Professor, Cardiovascular Physiology at Montreal’s Concordia University, "... what happens to an elite athlete after one week, might take a sedentary individual one or two months to experience. " The precise extent you will lose your fitness depends upon how long you are in the detraining phase and where you are on the fitness bar.
   The good part is that no matter the cause for your falling off the workout wagon—laziness, exhaustion, illness, conflict in schedules, injury, etc.—these conditions can most likely be reversed if you resume your exercise routines and healthy living. So what’s a body to do? You get off that couch and get back on a consistent exercise routine. Just thirty minutes of daily aerobic activity strengthens your heart, improves your whole body and core mobility. (25) If you are injured, sick or bed ridden, talk with your doctor and therapist to find out what kind of exercises you can safely perform. Failure to exercise is a life threatening choice, especially when you just stop abruptly.
