Honest limits
What this study does not prove.
This association does not establish one cardio prescription for everyone, but it supports training cardiorespiratory capacity consistently.
Kris's practical takeaway
Here's what to do with it.
For lifters who hate cardio, this is the adult-health argument: cardiorespiratory fitness is not just about burning calories.
Ways to use it
Safe ways to apply it.
Cardio is not just a calorie tool

Related questions
Questions this research helps answer.
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 healthy-aging levers, but workouts do not reverse time. Physical activity, strength, and cardio are still among the most actionable ways to support health and function as you age.
