I, too, am coming off a nasty virus that knocked me down. The last workout I did was STS Total Body on Monday, Jan. 28th. That night I came down with a high fever and was flat on my back for 5 days.
It's been a week now and I finally feel like I can actually do a workout. I was wondering what one I am going to do???? I know I need something total body. I was thinking of doing CrossFire and modify, but the more I think about it, the more I think it might not be such a good idea, even modified.
I think the best thing for me to help me get my strength back up and in the groove is going to be a total body weight workout. It won't get me as sweaty, but it will still challenge me. However, it won't push me as much as a cardio will. Then I will try cardio tomorrow.
Best wishes!
