Hello. I'm kind of an avid runner. How about you?
I actually don't like running that much, but I do it anyway.
They say it's better to do a short run than a long jog.
Do you think that's because your heart rate is quicker during a short run?
You get benefits to your metabolism from running, while not so much with jogging.
The way your feet move is different when you jog versus when you run. It makes you more stable at jogging speeds.
You get pretty much the same exercise walking as jogging, and less harm to your joints.
Exercise in general can keep your body healthy and prevent heart disease. It's better to do a little than nothing at all!
