That just means the walls of the heart would need to grow thicker. Are they at the limit already?

Wall thickness increasing by x increases cross section/power by x^2, but also increases chamber volume/workload by x^3. So workload outruns available power. It's because of this people abusing steroids get heart failure eventually.

    What do you mean by workload? Are you referring to the oxygen cost per stroke, or what?
