Probably the same way (as someone suggested on these boards recently) that practicing "Martial" arts doesn't imply worship of Mars.
If you want to look into it more, do some TACHIYOMI at Borders in one of Draeger's trilogy (sorry, forget which one). He comments at some length on the difference between "KEIKO" and "RENSHU", roughly practice and training if I recall aright.
