Questions that cite this source.
Cardio longevity answer
Should you prioritize cardio for longevity?
Cardiorespiratory fitness is strongly tied to health outcomes, so cardio deserves a real place in the plan. But for a regular lifter, the answer is not cardio instead of weights. It is cardio placed intelligently alongside strength training.
Biological aging answer
Can exercise slow biological aging?
Exercise is one of the strongest practical anti-aging levers, but biological-age language needs caution. The useful takeaway is not that workouts reverse time. It is that physical activity, strength, and cardio are still the most actionable fitness-span tools.
