Last month, my husband got a really bad sinus infection. We had just started round 2 of Insanity: Max 30. Of course. I knew as soon as he was sick that I was going to get sick, too. Was I right or was I right? Two days after he got sick, I got sick although not as bad as hubby. So, I took off time from my workouts to recover from being sick. Took me about a week to get better.
