Your heart does work like that. If you work out often, especially in world class tournaments, you littarly get a bigger heart. If you then suddenly quit exercizing it can lead to verry sireus issues

The heart doesn’t get a rest and never stops beating. This makes heart muscle remodelling particularly hard. Generally when the heart tries to remodel, it does it pretty poorly. Over your lifetime, that remodelling can lead to problems like abnormal heart rhythms or leaking valves.
