PCOS Question

I have a roommate who has PCOS. I am wanting to workout and my roommate wants to work out with me. Well we got our workout routine schedule for the next 8 weeks. and after one day of doing the work out, she came out of nowhere stating that she can’t workout because it’ll produce this hormone that is similar to testosterone that will make her bigger. Normally if someone claimed that I would’ve gone with it, but coming from her I don’t really believe it. Only because I have caught her in lies before. But if it is true and I’m just being a jerk, I would like to know. And for those of you with PCOS how do you work out?
