Exercise Variety Matters: Mixing Activity Types Linked to Lower Mortality Risk

Does the Type of Exercise You Do Affect How Long You Live?

A study published in BMJ Medicine in April 2026 examined data from two large prospective cohort studies to investigate whether the variety of physical activities a person engages in matters for longevity, independent of total exercise volume. The researchers found that participants who regularly performed multiple types of physical activity — such as combining aerobic exercise, strength training, and flexibility work — had a measurably lower risk of all-cause mortality compared to those who focused on a single activity type.

This finding builds on longstanding WHO physical activity guidelines, which recommend that adults accumulate at least 150 to 300 minutes of moderate-intensity aerobic activity per week, supplemented by muscle-strengthening activities on two or more days. While meeting these minimum thresholds is well established as beneficial, the new research suggests that how people distribute their activity across different modalities may be an underappreciated factor in health outcomes. The study adds to a growing body of evidence that exercise diversity — not just duration or intensity — plays a meaningful role in disease prevention.

What Types of Physical Activity Provide the Greatest Health Benefits?

The WHO has long identified physical inactivity as the fourth leading risk factor for global mortality, contributing to an estimated 3.2 million deaths annually according to its Global Health Estimates. Previous research has consistently shown that aerobic activities like walking, cycling, and swimming reduce cardiovascular disease risk, while resistance training helps maintain muscle mass, bone density, and metabolic health. The BMJ Medicine study reinforces that each activity type contributes distinct physiological benefits that may not be fully replicated by other forms of exercise.

From a clinical perspective, the findings have practical implications for public health messaging. Rather than simply advising patients to "exercise more," healthcare providers may achieve better outcomes by encouraging variety — for example, recommending that a dedicated runner also incorporate strength training and stretching into their weekly routine. The researchers noted that activity variety may improve health through multiple complementary mechanisms, including enhanced cardiovascular fitness, improved insulin sensitivity, better musculoskeletal function, and reduced systemic inflammation. This aligns with existing guidelines from the American Heart Association, which already recommend a combination of aerobic and resistance exercise for optimal cardiovascular health.

How Can People Incorporate More Exercise Variety Into Their Routine?

For individuals who currently engage in only one form of exercise, the transition to a more varied routine does not need to be dramatic. Public health experts recommend starting by adding one new activity type per week. For example, someone who walks daily could add two sessions of resistance training using bodyweight exercises or light weights, plus one session of yoga or tai chi for balance and flexibility. The key insight from the BMJ Medicine study is that even modest diversification appears to confer additional health benefits beyond those achieved by increasing the volume of a single activity.

Importantly, the study's findings do not diminish the value of any single form of exercise. Any physical activity remains far better than none, and the WHO estimates that if global physical inactivity were reduced by just 10 to 25 percent, millions of premature deaths could be averted. However, for individuals already meeting minimum activity guidelines who want to maximize their health benefits, adding variety to their exercise routine represents a low-cost, accessible strategy. The research also highlights the potential value of community-based programs and group fitness classes, which naturally expose participants to multiple activity types and may help with long-term adherence.
