Personally I avoid workouts when I have a cold, as it tends to go to the lungs if I don't take it easy. Just going to work slows down my recovery time quite a bit. I missed a ton of workouts lately, but have made suprisingly good progress thanks to EDT, which have consistently been some of the best workouts I've ever had.
1 Month and 1/2 Ago: Started EDT, performed workouts for 2 weeks.
1 Month Ago: Caught a nasty stomach virus, no exercise for 7 days. Not that anal about my diet. I just kept my protein levels up, avoided obvious junkfood, and tried to eat clean.
3 Weeks Ago: Resume workouts. Strength levels up, bodyfat down, biceps, triceps, traps, back appear bigger.
1 Week and 1/2 Ago: Catch a nasty cold, no exercise for 10 days. 4 days ago I notice my pecs look bigger than before. My midsection looks better than ever, but still a ways off. The first 5 days I maintained my usual diet, but then fell off the wagon. Too many complex carbs for no activity, some junkfood. One day I had a piece of chocolate cake, another day wholegrain pancakes with butter in the evening, etc. But, I was good about my protein, fats and veggies.
Today: Finally got back to the gym. My legs/lower back failed sooner than I would have liked, but I still made a decent volume increase. I'm bloated from the last few days of eating, but today my diet was perfect and hopefully I'll be ahead in a week.
