I find I do best every day. I do try to mix it up though. I do try to get a good cardio work out ever M, W, F, and then I will do Pilates or strength training, or just a brisk walk on the other days. I try to go for a regular stroll every day. I know it's not really vigorous exercise, but it gets me up off the sofa and out of the house and prepares my mind for life outside the box. If I don't exercise every day, I get sore and lazy and then one day becomes two and so on. Today, I am feeling the effects of my flu shot and am hoping by 3:00 I feel better so I can get to the gym with DD and her Girl Scout Troop, and squeeze in a cardio workout. I won't beat myself up about it if I don't, I'll just make myself do something extra tomorrow.
Keep the Faith!
