I'm not a doctor, but I believe the thickening in the heart is,
unlike most other developed musculature, profoundly unhealthy.

You want to be able to deliver the most amount of oxygenated blood
with the least cardiac effort. If your heart is thickening then this
is no longer happening.

Overall exercise would incrase the efficiency of circulation and oxygenation
in the body, reducing demand and stress on the heart.
