Swimming vs Walking in Perimenopause: Which Exercise Suits You Better?
Swimming and walking both benefit perimenopausal women, but in different ways. Compare bone density, joint health, cardiovascular benefits, and accessibility.
Why Exercise Choice Matters More in Perimenopause
Exercise becomes more important and, for many women, more complicated in perimenopause. Joint pain increases for many women as estrogen declines and its anti-inflammatory effects diminish. Bone density begins to drop at a faster rate. Cardiovascular risk starts to rise. Sleep, mood, and cognitive function all benefit from regular movement. Against this backdrop, choosing the right type of exercise matters more than it might have in your thirties. Swimming and walking are two of the most commonly recommended activities for perimenopausal women because both are accessible, low-risk, and adaptable to a wide range of fitness levels. They also happen to be meaningfully different in the specific benefits they deliver. Understanding how they compare across bone health, joint stress, cardiovascular training, symptom management, and social connection helps you choose the approach that best fits both your body and your life right now. Most women will find that a combination of both, or one alongside resistance training, serves them better than either in isolation.
Bone Density: Where Walking Has the Clear Advantage
One of the most important health concerns in perimenopause is protecting bone density. Estrogen plays a direct role in bone formation and resorption: as it declines, bone loss accelerates, with the fastest rate of loss occurring in the years immediately around the final period. Exercise that stresses bones through impact signals the body to maintain or build bone tissue, a principle called Wolff's Law. Walking is a weight-bearing activity, meaning each step applies a ground reaction force through the skeleton. Research consistently shows that regular walking preserves bone density in the hips and spine and reduces fracture risk in postmenopausal women. Swimming, in contrast, is a non-weight-bearing exercise. The buoyancy of water supports the body, which is excellent for joints but means bones experience minimal mechanical loading. Studies comparing swimmers to non-exercising sedentary controls show some benefit, but swimmers consistently have lower bone density than runners and walkers of the same age and fitness level. If bone density is a priority, which it should be for most perimenopausal women, walking delivers a benefit that swimming simply cannot match.
Joint Health: Where Swimming Excels
For women experiencing joint pain in perimenopause, swimming offers a profound advantage. Water supports approximately 90% of body weight in chest-deep water, dramatically reducing the load on hips, knees, ankles, and the spine. This makes swimming one of the very few vigorous cardiovascular activities that can be performed without aggravating arthritic or inflamed joints. Women with osteoarthritis, joint hypermobility, significant knee pain, lower back issues, or plantar fasciitis often find swimming is the one form of exercise they can perform consistently without symptom flare. The resistance of water also provides gentle muscle strengthening through full range of motion, supporting joint stability without high impact. Walking, while generally low-impact compared to running, does apply repeated load to joints. For women whose joint pain is mild, this is not a problem and the bone density benefit of walking outweighs the joint loading concern. For women with moderate to severe joint pain, swimming allows maintenance of cardiovascular fitness and muscle tone while the joints are protected, making it a genuinely important option rather than simply a consolation choice.
Cardiovascular Health, Hot Flashes, and Symptom Effects
Both walking and swimming provide cardiovascular benefits when performed at appropriate intensity. For cardiovascular training, intensity matters more than format: a brisk walk that raises heart rate into the moderate zone (roughly 60 to 70% of maximum) delivers similar cardiovascular adaptations to a moderate-pace swim. The cool water in swimming pools has an additional specific benefit for perimenopausal women: many report that hot flashes are less frequent or less severe on days they swim, and the cooling effect of water provides immediate relief from thermal discomfort. This makes swimming particularly attractive for women whose hot flashes are prominent during and after exercise. Walking in warm weather can trigger hot flashes in susceptible women, and this sometimes acts as a deterrent to exercise on warmer days. Walking has its own mood and cognitive benefits, partly through the social aspect, partly through nature exposure when walking outdoors, and partly through the meditative quality of a regular outdoor movement practice. Nordic walking, which adds poles, increases upper body engagement and caloric expenditure and may offer additional bone loading through the arm action.
Accessibility, Cost, and Practical Barriers
Walking wins on accessibility by almost every measure. It requires no equipment beyond supportive footwear, no facility access, no travel to a pool, and no membership fees. It can be done at any time of day, in any weather with appropriate clothing, alone or with company. The threshold to get started is extremely low, which matters enormously for adherence. Walking can also be incorporated into daily life rather than treated as a separate session: walking to work, taking the stairs, or taking a walk at lunch contributes meaningfully to total activity without requiring dedicated time. Swimming requires access to a pool, a swimsuit, and ideally goggles. Pool access varies considerably by location, and costs can be significant over a year. Pool opening hours restrict when you can swim. Hair care concerns, chlorine sensitivity, and the logistical overhead of changing and showering all reduce adherence for some women. That said, many leisure centres offer concession rates and women-only sessions, which can improve accessibility and comfort. For women who already swim or live near affordable facilities, the barriers are minimal.
The Best Approach: Combining Both and Adding Resistance
The most effective exercise strategy for perimenopause rarely involves choosing just one activity. Combining walking and swimming addresses more of the key physiological needs than either alone. Walking provides the bone-loading impact that swimming cannot deliver. Swimming provides the joint-protective cardiovascular and muscular training that high-impact options cannot match for women with joint pain. Together they provide variety, which reduces the psychological monotony that leads to dropping exercise routines. However, neither walking nor swimming provides adequate stimulus for muscle mass preservation, which is perhaps the most critical exercise goal in perimenopause. Resistance training, whether in a gym, at home with bands and weights, or in the form of reformer pilates, must be included for most women to maintain the muscle mass that protects metabolic health, bone density, and functional independence. The evidence for resistance training in preserving muscle and bone through perimenopause and beyond is stronger than for any other single form of exercise. A practical weekly pattern for many women is two to three resistance sessions, two walking sessions of 30 to 45 minutes, and one to two swimming sessions, adjusted to individual capacity, time, and joint tolerance.
