Calif Bill stated correctly that Cusco is at a higher altitude than Machu
Pichu. Some people will experience mild altitude sickness in Cusco, but it
is unlikely in Machu Pichu.
Most people will be unaffected in Cusco, except maybe they will have a
headache, and of course short breath.
Exercise is good for your health, of course, but it has strictly no effect
on altitude sickness, which is related to the red cell count in your blood.
To adapt to altitude, there is only one way : go up slowly, rest a lot,
drink a lot, and wait until your marrow has manufactured more red cells. It
may take a few days. And don't expect to be immune to altitude once you have
adapted : your cell count will go back down within a few days, if you go
down.

A fit person is less prone to altitude sickness than one who is not.
Yes, altitude sickness is related to red cell count, since it is those
cells that deliver oxygen to the brain, and altitude sickness is
due to reduced oxygen in the brain, but a fit person will have a higher
red cell count and a greater oxygen uptake due to a more efficient cardio-
pulmonary system than an unfit person, all other things being equal.
That's one of the reasons the fit tire less easily, can exert themselves
harder for longer, and recover more quickly than the unfit.
Now, I'm not saying that fit people are immune to altitude sickness, just
less prone to it. Also, another advantage of being fit is that a well
trained body will adapt more quickly to the higher altitude.
The best advice for anyone, fit or not, is to take it easy and not let
your enthusiasm to "see everything" push you beyond safe, reasonable
limits.
Plus, by "...drink a lot..." I'm sure you mean water. ;-) Alcohol impairs
the brain's ability to absorb oxygen. And at high altitude that can be a
very dangerous drunk.
