voluntarily creating problems for your body so it gets better at solving them
means Physical activity performed to improve or maintain fitness and health, or more broadly the act of putting something to use or practice.
from From Latin exercere, 'to keep busy, drive on, train,' built from ex- ('thoroughly') and arcere ('to hold off, restrain'). The original sense was something like 'to set in motion by removing restraint' — fitting for a word that now means deliberately unleashing effort on yourself. It reached English in the 14th century by way of Old French exercice.
