I'll have to ask my brother in law whether he'd rather have another quadruple bypass or run a marathon. Which he thinks would be easy to recover from.



Looking at creatine as a marker of kidney damage in the context of exercise is questionable. With a heart attack, oxygen deficit forces the heart to turn to non-oxidative sources of energy--this leans hard on creatine phosphate for quick short term salvage of atp levels, thus there's an increase in blood creatine. There's the heart muscle trying not to die, and then there's skeletal muscle doing what's needed to sustain a certain effort.

Balance is the key...doing too little and you don't get results..doing too much and you invite problems

Like.
I didn't know until a college course taught by a exercise physiologist who trained elite athletes that exercise over-training was even an issue. All the rest of us ever heard about was the usual big organizations harping on getting out and doing more, more, more fitness, but this message was really meant for the large audience of typically sedentary people who would benefit from just doing something more, not athletes already doing so much that sports injuries were a big issue and for whom more was...risky. I'm glad to have received this heads-up about the risks earlier on because nowadays as an older person I do need to be more cautious to strike that balance between enough and too much to where an injury might sideline me from being able to continue doing the enough.

No one here has that I can see. But at least we can stop beating ourselves up for not being runners. I've hated running since puberty. It never felt good to me.

Yeah--it was pretty much a stretch for me, too. I'm not built for it. These days I watch the skinny/wiry/mostly young people running with gazelle-like grace and think, "I'm glad I gave that up!" I was NEVER a gazelle.

P.S. When I spot a large person trying to jog off the weight, I want to say, "Stop! It won't work and you'll ruin your knees."

Imma not a runner (bad knee since age 12) but I can burn up the miles walkin' or bikin' w/o any problem whatsoever!

On a lighter note:

If Imma running, you'd better run too b/c something is chasing me!!
