I also incorporate some sprinting in there, I'd say about 4-6 times depending on how I feel. I can never run that far, but since I'm already warmed up I no longer get side stitches, which is great.
Anyway, I have one problem. I'm not sure how far I'm walking, but once I get to my spot (where I turn around, and walk back home or to my parents' house) my right ankle starts to hurt BAD. So bad I have to limp a good bit back. Sometimes both ankles hurt. But they only hurt when walking. When I run, and lift my knees up high they don't hurt.
I was wondering if I should be worried. I can tell it's not a real injury, because it usually goes away once I sit down afterward. But the whole way back home, it hurts really bad, so bad I have to take a breather and stretch out my legs. Does this happen to anyone else?
I do walk pretty fast. I try to keep my heart-rate around 140-176. I'm not sure if that's good or not. My resting heart rate is usually around 60-90 depending on how active I am.
My heart-rate monitor says I usually burn between 250-300 depending on my efforts. I know it's probably off, since I can't type in my weight and height into it, and can only type in my age and gender. Thanks.
