He is both an experienced fighter AND a mage. A very, very powerful one at that. He probably was the most powerful mage alive during the Saga (he easily keeps Yennefer in check, and she is one of the top tier spellcasters alive at that point, canonically). Hell, he learned things that were otherwise only known to the elven Sages. It could be easy for such an individual to use magic to improve his own physical abilities without using mutations of various kind.
