Good point, and to clarify, everybody has a genetically set ratio of fast/intermediate/slow twitch muscles; and all you can do is strengthen them up because you can't increase the number of each of those muscle fibres.

The ratio of your fiber type is a result of:

(2) Transformation of slow to fast or fast to slow through training influence.
