My pregnancy is my training, apparently

I was going through some of my past research on the effects of pregnancy on the body of an athlete and thought this should cheer me up (and others, if you're struggling like me):

Pregnancy does, in fact, have a training effect on you much like exercise does. It is nicely graduated as the baby grows, and unlike your exercise routine, there is no taking a day off!

Here are some of the systems in your body that are enhanced by pregnancy:

• Cardiovascular: During the course of pregnancy your blood volume increases by about 40 percent and your heart rate increases about 15 beats a minute to supply the growing baby with nutrients and oxygen. This is the equivalent of doing mild exercise 24 hours a day over 40 weeks, adding just a little more load each day.
  
• Breathing: Your respiratory rate increases, thus raising your oxygen uptake.
  
• Musculoskeletal: Your skeletal system strengthens in response to the progressive weight training that the baby affords. At the same time, the hormone relaxin, released to expand the pelvis for the birth, will make you the most flexible you have ever been in your life, and you can get a real jump-start in your stretching routine.
  
• Hormones: Your body pours out huge amounts of hormones to support and strengthen itself and the developing fetus.

So basically, I expect to improve my sprint, olympic and half Ironman tri times by 10s of minutes next season!
