Why Harvard Experts Say This Gentle Exercise Beats Walking and Running
For many people over 55, staying fit can feel like a challenge. Joints become more sensitive, recovery time increases, and the risk of injury rises. While walking and running are often the first exercises that come to mind, Harvard University experts suggest that there’s a far better, low-impact activity to maintain strength, balance, and overall health — swimming.
According to research from the Harvard Medical School, swimming engages nearly every muscle group in the body without putting stress on the joints. It strengthens the heart, improves lung capacity, and enhances flexibility — making it the perfect exercise for older adults who want to stay active safely.
The Full-Body Benefits of Swimming After 55
Swimming is more than just a recreational activity — it’s one of the most complete workouts available. Each stroke involves the arms, shoulders, core, and legs, giving the entire body a balanced workout. The buoyancy of water supports your body weight, reducing impact on the knees and hips, which makes it ideal for people dealing with arthritis or joint discomfort.
Dr. I-Min Lee, professor of epidemiology at Harvard, explains that “low-impact aerobic exercises like swimming provide cardiovascular benefits comparable to running, but with significantly less strain on the body.” In other words, swimming helps you maintain endurance and strength without the wear and tear associated with more intense workouts.
How Swimming Keeps You Younger, Stronger, and More Flexible
One of the reasons Harvard experts recommend swimming is its ability to combat muscle loss — a common issue that begins in middle age and accelerates after 55. The resistance of water forces the muscles to work harder without causing fatigue or pain, improving tone and balance at the same time.
Additionally, swimming helps maintain flexibility and joint mobility. The repetitive stretching movements of each stroke promote better posture and coordination, reducing stiffness and improving range of motion. Regular swimmers often report fewer aches and greater ease in daily activities like climbing stairs, bending, or carrying groceries.
Boosting Heart and Brain Health
Beyond muscle tone, swimming has major cardiovascular benefits. It increases heart rate, improves circulation, and helps control blood pressure and cholesterol levels. A study published by Harvard Health found that adults who swim regularly have a 40% lower risk of heart disease compared to sedentary individuals.
Moreover, swimming is also linked to improved brain function. The rhythmic breathing and repetitive motion encourage relaxation, which helps reduce stress and anxiety. The increase in oxygen flow also supports cognitive function and memory — key factors for healthy aging.
Safe for Every Fitness Level
One of the best things about swimming is that it’s suitable for everyone, regardless of fitness level or physical limitations. You can start slowly with simple movements, such as walking in water or performing gentle aqua aerobics, and gradually progress to more structured laps or water resistance workouts.
For those who don’t have access to a pool, Harvard specialists suggest water-based exercise classes, often offered at local gyms or community centers. These classes use the natural resistance of water to provide a low-impact yet highly effective workout that protects the joints and builds endurance.
Other Harvard-Approved Alternatives
While swimming takes the top spot, Harvard’s researchers also highlight other activities that deliver similar benefits for adults over 55:
- Cycling: Excellent for cardiovascular health and lower-body strength with minimal joint impact.
- Pilates: Enhances balance, posture, and flexibility while strengthening the core.
- Tai Chi: A mindful movement practice that improves coordination and reduces fall risk.
All these exercises share one key principle — they keep the body active without overloading it. Regular participation, even just 30 minutes a day, can dramatically improve quality of life, energy levels, and mobility.
How Often Should You Swim?
Harvard experts recommend swimming or engaging in similar water-based activities at least three times per week. Sessions can range from 20 to 45 minutes depending on stamina and comfort. Always begin with a warm-up, and if you’re new to swimming, consider starting with basic movements like floating or gentle kicks to build confidence in the water.
Over time, consistency is what brings the greatest rewards — not intensity. It’s better to swim gently and regularly than to push too hard once in a while.
Final Thoughts: A Gentle Path to Strength and Longevity
Harvard’s advice is clear: staying fit after 55 doesn’t mean pushing your limits or risking injury. It’s about finding exercises that nurture your body while strengthening it. Swimming, with its blend of cardiovascular, muscular, and mental benefits, fits that role perfectly.
Whether you swim laps, join a water aerobics class, or simply enjoy moving through the water, this simple yet powerful activity can help you remain strong, flexible, and full of vitality for years to come.
So next time you think of exercise, skip the running shoes — and grab your swimsuit instead.

One thing about swimming at that age is that is a very low impact activity, it’s incredibly important to supplement it with resistance training for bone density purposes
I found swimming to be good exercise, and I also like water aerobic exercising.
