Back in business again?

First day of exercise after my health crash last week. I did 60 min of Core. I thought it was going to be very light since I'm used to do body pump, spinning and indoor walking. But I was wrong. It is incredible how much strength you can loose by puking your guts out. Last week I barely managed to stay awake at work and that is a strange feeling for me. I like my work, I have fun at work, I longed back to work after 3 weeks of holiday. And when I finally got back after 3 weeks + days of sick leave I didn't have any fun at all. Luckily it lasted only for a few days. Now I'm back in business again... hopefully...
