Brumation+Handling=Bad Idea???

I have a wild black rat snake who is 4ft in length and very healthy. Iv had her for about 2 months now and she seems to be in brumation mode. She is oddly very docile for a wild snake, she has never struck but has rattled her tail, other than the rattling she shows no signs of aggression.

Now the question. Im really eager to get her trained with handling, and i havnt handled her since i got her. Is it a bad idea to handle her during her brumation period? Or should i just be patient and wait untill spring rolls around?

Thanks
