The thing is, you want great cardio capability. https://jamanetwork.com/journals/jamanetworkopen/fullarticle...

> Extreme cardiorespiratory fitness (≥2 SDs above the mean for age and sex) was associated with the lowest risk-adjusted all-cause mortality compared with all other performance groups.

Sure your cardio might be "good" now, but see Table 2 for what happens to you over time (with and without training).

Put more plainly https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6153509/

> Individuals with higher cardiorespiratory fitness (CRF) showed lower risks of all-cause, CVD and cancer mortality; those with higher grip strength (GS) had lower all-cause mortality. All-cause and CVD mortality risk was lowest in adults with both higher CRF and higher. Improving both CRF and muscle strength, as opposed to either of the two alone, may be the most effective behavioral strategy to reduce all-cause and cardiovascular mortality risk.
