I have been walking anywhere from 9 to 18 miles a week for the last year. It's helped me physically with weight loss, general health (lower blood pressure, slower resting heart rate) but most importantly, it's helped me mentally. I feel stronger, more in control of myself. But for the last week I have been tired. Like my legs just feel tired and kind of heavy. I've been doing a lot (and I mean A LOT) of yard work so I don't feel like I've really missed a workout but my body is tired. I'm torn between listening to the part of my body that says, you're tired go lay down and the part that says get off your lazy *kitten* you know you'll feel better if you do. I've been going shorter distances when I do walk but it feels like failure even though I know it's not. Anyone have similar experiences?
