Mutations in the germ cells (cells that produce sperm and eggs) can be inherited if the sperm or eggs thus produced go on to produce an new individual. Mutations in somatic cells (all the other cells in the body) aren't inherited because they don't produce new individuals.

They are only inherited if there is a mutation *in the gametes*

If lets say your cells have been mutated *during your lifetime* (eg. exposure to UV radiation, whatever) then they cannot be inherited....because it happened during your lifetime...this is called "acquired traits," which no one believes anymore.

JUST LIKE lets say I go to the gym and work out...does that mean my offspring are going to be buff like me? No, because what happened was *during my lifetime*.
 
mutations happen on accident
changes inherited are genetic traits from mom and dad combining

like when playing sports, you mean to throw the ball straight, but something wierd happens and you throw it off course, even though you throw it straight most of the time.
the body gets stuff right most of the time, but there are some lapses
the body often has many ways to self correct. rarely does a mutation during a body function like dna replication, protein synthiesis, mitosis etc...
