Copa - I am a runner. I started out a walker, and still walk quite a bit as well as run. To vary it and so my body doesn't plateau, I throw in yoga or what I call a "static" day - weights, squats, ab work, etc. When I first started, I started with p90x. I stuck with it but it was so hard. I couldn't even finish the workouts at first but I did as much as I could. Then I discovered I prefer to be outside and running was natural. I am super active outside in spring and summer, which helps.
Yes, even being healthy and exercising, I do get overwhelmed with fatigue at times and can lay a day away. I think it is age, stress and hormones. I make myself get up and do a little something no matter what. Most days I feel great and have a ton of energy, but yes, life crashes over me from time to time.
