I am not a dr. or nurse, but.......
Fitmum, I don't think it's wise to do so. Because I feel no matter what you do, be it cardio or weight training, you're more likely to work up a sweat and your pores will be wide open. And maybe this is a country thing as my dh would always say, but I think the cold sweat will settle in your joints/bones and causing the flu to linger longer?????????????
I don't want you to get a relapse. Take it easy.
