Okay... so, jogging (possibly jogging, plus a mildly intense heart-rate raising exercise session the next morning) can make me feel wiped out.|
What about just walking? I'd assumed it could, but I counted "walking" as including "slower than normal on my big-hills workouts on my treadmill". And that got my heart rate reaching pretty high levels, even if my feet weren't moving as quickly.
So yesterday, for multiple reasons, I walked 10 miles, combined outside-walking + treadmill, with a goal of keeping my heart rate low(ish).
I'm tired, but I don't think I'm fatigued. And yeah, my legs hurt, and my feet are doing a kind of "hey, boss, you didn't give us time to develop a healthy layer of callus!" But I don't think I'm getting the kind of exhaustion I'm afraid of.
I'm going to try to do "enough" walking today to give that a good test - if I can manage an hour walk while watching movies, that'd be great. Then we'll see if this was a wise (if painful) choice, or a really bad choice, tomorrow.
If walking is safe, it sounds like heart-rate might be key, and I might be needing to do exercises that are less heart-intensive.
This isn't awful, by the way. Getting one's heart rate up to the 120s to 130s is more than enough to strengthen it. But if you push your heart rate into the 140s and higher and keep it there, you can be burning in the region of a thousand calories an hour, versus 5-600 an hour from less intense exercise. And for numbers-junkies, it's nice to see larger numbers pile up more quickly. Plus, intense exercise is known to help release fat from the liver and abdomen. Less intense exercise isn't. Then again, maybe it's because there aren't enough people stubborn enough to do less intense exercise long enough to make it happen.
