The EA SPORTS Active programs have some great tips in them and the More Workouts, which was released in October, really stepped up the game by adding in the warm up and cool down routines in the workouts for every day.
In reading this article, 10 Fitness Habits You Never Knew Were Bad, I think there are many good points for all of us who use the Wii workout programs that we wouldn't otherwise hear because we're not going to a gym and getting a real live trainer. For instance, point number 1:
Not eating breakfast – consider that by the time you wake, at least six hours has passed since your last meal — and you’re also probably dehydrated. Top that off with a cup of coffee and now you’ve just spiked your energy levels. With no foundation to carry you until lunch, you end up gorging anything when you do have lunch. Your body is starving for nutrition and nutrition gives you the energy you need to workout (effectively). The Institute for Integrative Nutrition, cleverly identifies breakfast as having the capacity to "literally break your fast after sleeping all night." If you’re not a breakfast person, become one. Start small. Prepare oatmeal on the weekends, refrigerate and use in a protein shake during the week. Add some healthy, low-fat yogurt and you now have a nutrient dense morning meal that will carry you until lunch. Muffins, Danish or croissants contain zero nutritional value. Tip: keep a jar of peanut butter at work and eat with an apple or mix some in with yogurt.
I did a 400+ calorie workout today. I've never been one to really take the whole stretching before and after bit seriously. But I have been the past week or so and this article really emphasizes why that is so very important.
