# Aerobic Exercise Plus Lifting Was Linked to Lower Mortality

> In nearly 100,000 mostly older U.S. adults, meeting aerobic guidelines and reporting weightlifting was associated with the lowest mortality, but the observational study cannot prove the exercise caused the difference.

## The 60-second version

In an older U.S. cohort, combining guideline-level aerobic activity with weightlifting was associated with the lowest all-cause mortality.

**Key points**

- The analysis included 99,713 adults with a mean age of 71.3 years and a median nine-year follow-up.
- Aerobic activity without lifting was associated with 32% lower relative risk versus neither activity.
- Aerobic activity plus lifting once or twice weekly was associated with 41% lower relative risk versus neither activity.
- Activity was self-reported once, and observational data cannot establish causality or a personal life-extension guarantee.

**Verdict.** A useful reinforcement of established aerobic-plus-strength guidance, with exact percentages that should stay attached to this specific observational cohort.

## Full explainer

> **⚑ Caveat:** This was an observational study using one self-reported activity questionnaire. The results show associations, not proof that exercise caused the mortality differences.


### Bottom line — What the cohort showed

Among 99,713 participants followed for a median of nine years, the lowest adjusted all-cause mortality was seen in people who both met aerobic activity recommendations and reported weightlifting. The participants were mostly older U.S. adults, with a mean age of 71.3 years.

- **99,713** — participants
- **9 years** — median follow-up
- **28,477** — all-cause deaths


### Results — How to read the percentages

- **Aerobic target, no lifting:** HR 0.68, or 32% lower relative all-cause mortality versus neither activity.
- **Aerobic target plus lifting 1–2 times weekly:** HR 0.59, or 41% lower relative all-cause mortality versus neither activity.
- **Weightlifting after accounting for aerobic activity:** HR 0.91, or 9% lower relative all-cause mortality.
- **Cancer mortality:** No lower risk after aerobic activity was taken into account.

A hazard ratio is a relative comparison across follow-up. It is not a promise that an individual will live a certain number of years longer, and it does not provide an absolute benefit without baseline risk.

> The combination had the strongest association; the study did not assign the combination at random.


### Design — What was actually measured

Participants recalled their aerobic activity and weightlifting during the previous year. Aerobic minutes were estimated from frequency and duration categories. Lifting was recorded by frequency, but not session duration, load, sets or repetitions.

- Exercise was measured once even though habits change over time.
- Healthier people may be more able to exercise, leaving reverse causation and residual confounding.
- The cohort was predominantly non-Hispanic White and came from a cancer-screening trial.
- The mean age was over 70, so exact estimates may not generalize to younger or more diverse groups.


### Practice — What the evidence supports

The result reinforces established guidance: when medically appropriate, combine aerobic activity with muscle strengthening rather than treating them as substitutes. Build gradually and seek tailored advice if age, frailty, pregnancy, injury or chronic disease changes what is safe.

- **Moderate aerobic activity:** Guidelines recommend 150–300 minutes per week.
- **Vigorous aerobic activity:** An alternative is 75–150 minutes per week, or an equivalent mix.
- **Muscle strengthening:** Guidelines recommend at least two days per week for major muscle groups.

The study's lifting category of one to two times weekly does not map perfectly onto the guideline threshold, so the public-health recommendation should come from the guideline, not from reverse-engineering the cohort result.
