No, no, look at the positive side. I am getting free core muscle
training :-)

Or straining your back picking up the penny :-)


My lower back isn't that great but MTB riding actually helps it by
building up core muscle. Something none of the doctors ever told me.
Most likely they didn't even know such stuff.

Just about anything that exercises a muscle strengthens it. I suspect
that your doctor knew that.


No, I was told MTB riding is out. They also did not know that I had a
magnesium deficiency, all of them didn't. A CPA did. After his advice I
started taking supplement and that helped, big time.

And how did this CPA determine that you had a magnesium deficiency?
did he do tests?

It seems many medical doctors learn by rote and then whatever they
learned in school goes.

Of course they learn by rote. Just as you did. Watts are volts times
amps, or did you discover that by experiment and your name is "James"?

He probably also knew that suggesting that you did bending and
stretching exercises every day was an example of futility on his part
as almost everyone will ignore any suggestion to do anything that
smacks of "work".

Well, no, the first three docs were in Germany and those guys generally
do not subscribe to a sedentary lifestyle. One actually suggested
swimming which was good advice though that doesn't do much for the back
muscles. At least not as much as MTB riding. My back muscles have become
almost rock-hard after five years of riding.

They would have become "rock hard" from lifting weights also. Did you
try that as part of a regimented exercise plan?

But this rock hardness must be a recent phenomena as it wasn't more
than a year ago that you wrote that you had to have a bike with rear
suspension because of your "bad back".
