Why Smoking would be stupid if you want to get in shape

When you do Cardio-Respiratory (or really any kind of) exercise, you breathe.  When you inhale, your lungs fill with oxygen.  That oxygen then is sent into your blood, re-naming the blood 'oxygenated blood'.  That oxygenated blood then travels throughout the body, dropping off oxygen to muscle fibers that need the oxygen.  Once the oxygenated blood drops off its oxygen stores, it is then re-named 'de-oxygenated blood'.  The de-oxygenated blood then tarvels through the rest of its body course until it gets back to the heart.  Hoo-ray!
And now insert Smoking:
When you inhale, your lungs fill with oxygen.  Oh wait, you're smoking, so your lungs fill with toxins.  That toxic-oxygen then is sent into your blood, re-naming the blood 'oxygenated blood' (full of toxins). That toxi-nated blood then travels throughout the body, dropping off toxins into muscle fibers that need the oxygen...which are instead getting toxic chemicals. Once the toxi-nated blood drops off its toxins and tiny bits of oxygen stores, it is then re-named 'de-oxygenated blood'. The de-oxygenated blood then tarvels through the rest of its body course until it gets back to the heart.  It is then again filled with toxins, because of smoking.  Boo!

With all that being said, please reconsider smoking.  It will destroy your muscles and your body.  Smokers are literally sending toxins to the muscles instead of oxygen!  If you want to see good results, don't smoke!
