Could Variety Be the Missing Piece in Your Fitness Routine?

A lot of people approach exercise the same way they approach brushing their teeth: find a routine that works, repeat it every day, and stick with it. But new research suggests your body may benefit from something a little less repetitive.

According to a new study published in BMJ Medicine, people who regularly engaged in several different types of physical activity lived longer than those who stuck to just one form of exercise, even when both groups exercised for roughly the same amount of time.

In other words, the variety itself appeared to matter.

Inside the Research

Researchers followed more than 111,000 adults for over 30 years through two of the country’s largest long-term health studies: the Nurses’ Health Study and the Health Professionals Follow-Up Study. Participants regularly reported their exercise habits, allowing researchers to track not only how much people exercised, but what kinds of activities they consistently did over time.

Over the course of the study, researchers recorded nearly 39,000 deaths and found that people who mixed multiple forms of exercise into their routines had lower mortality rates than those who relied on just one activity. The group with the greatest exercise variety had a 19% lower risk of death from any cause, along with significantly lower death rates from heart disease, cancer, and respiratory illness.

The findings support something many exercise specialists have long suspected: different activities challenge the body in different ways, and relying on only one form of movement may leave important systems undertrained.

Why Your Body Benefits From Different Types of Movement

Walking helps cardiovascular endurance and circulation. Strength training protects muscle mass and bone density. Activities involving balance, coordination, or quick changes in movement — like tennis, pickleball, dance classes, or hiking uneven terrain — challenge stability and mobility in ways steady cardio often does not.

When you combine several types of movement, you create a broader physical foundation. That matters even more as we age.

The study found benefits across most forms of exercise, including walking, jogging, running, resistance training, stair climbing, and racquet sports. Weight training and resistance exercises were associated with lower mortality risk on their own, reinforcing growing evidence that muscle strength plays a major role in long-term health and independence.

For many people, though, sticking to one familiar workout simply feels easier. The same morning walk. The same treadmill routine. The same gym circuit every day. Familiarity is comfortable, especially when starting a fitness journey can already feel overwhelming.

But doing the exact same activity repeatedly may limit how much you challenge your body over time. Beyond physical benefits, variety can also help prevent boredom, reduce overuse injuries, and make exercise more sustainable long term.

What This Looks Like in Real Life

The good news is that “mixing it up” does not mean training like an athlete or spending hours in the gym. Small changes count.

If you usually walk for exercise, consider adding two short strength-training sessions each week using resistance bands, bodyweight exercises, or light weights. If you mainly lift weights, add activities that improve endurance and mobility, like biking, swimming, yoga, or brisk walks outdoors. If you love cardio classes, try incorporating balance or flexibility work alongside them.

The goal is not perfection. It is variety over time.

If you are unsure where to start, experts often recommend building around three core categories of movement:

• Cardiovascular exercise (walking, biking, jogging, swimming)

• Strength training (weights, resistance bands, bodyweight exercises)

• Mobility, balance, or coordination work (stretching, yoga, dance, sports, hiking)

Even rotating between a few activities throughout the week may help engage different muscles, joints, and energy systems more effectively than relying on a single repetitive routine.

Importantly, researchers emphasized that consistency mattered. The people who saw the greatest benefits were not simply trying random activities once or twice. They maintained multiple forms of movement regularly over many years.

The study does have limitations. Because it was observational, researchers cannot prove exercise variety directly caused longer life. Participants were also mostly healthcare professionals, and activity levels were self-reported. Still, the size and length of the study make the findings difficult to ignore.

You do not have to abandon the workout you already love. You just may benefit from giving your body a few new ways to move.
