I believe that you're body is like a car engine.
If you don't use it, and let it be in the ellements,
it will rust and fall apart. If you overwork it, it will break down as well.
When you/I do cardio, we filter more pollutants from our blood via
our liver kidneys ect. the more passes, the more pure.
You sweat, and realease toxins, and also you're cells get more O2.
You cleanse you're arteries, and they become bigger to handle all the extra blood flow.
You're bones joints get stronger, and I'm not stong to begin with, so I could easily turn into
a wimp
Everything in life becomes easier. You move with more grace
You dont tire as easily.
Fat people that have never really been in (decent) shape have no fucking idea
of what they are missing.
