Strength Training vs Yoga for Perimenopause: What Each Does Best
Strength training vs yoga for perimenopause: bone density, hot flashes, mental health, muscle, and flexibility compared. Learn how to combine both.
Two Very Different Types of Exercise, Both Valuable
Strength training and yoga represent opposite ends of the exercise spectrum in many ways. One focuses on progressive mechanical loading, the other on breath, movement quality, and stillness. Both are recommended in perimenopause, but they produce different outcomes. Understanding which goals each serves better helps women prioritise when time is limited, and makes the case for combining both rather than choosing one and ignoring the other. Neither is a complete solution on its own, and the strongest approach draws on what each does best.
Bone Density: Strength Training Wins Clearly
Bone responds to mechanical load by laying down new bone tissue. Resistance training, particularly compound movements like squats, deadlifts, and rows, creates the kind of loading stimulus that drives bone formation. Studies in perimenopausal and postmenopausal women consistently show that progressive resistance training improves or maintains bone mineral density at the hip and spine, the two sites most vulnerable to osteoporotic fracture. Yoga does not produce sufficient mechanical load to drive the same bone adaptation, though weight-bearing yoga poses offer some benefit. If bone density is a primary concern, resistance training must be part of the plan. Yoga alone is not sufficient for this goal.
Hot Flashes: Yoga Has the Stronger Evidence
For vasomotor symptoms including hot flashes and night sweats, yoga has a more consistent evidence base than strength training. Multiple randomised controlled trials have found that regular yoga practice reduces hot flash frequency and severity. The proposed mechanisms include nervous system regulation, reduced stress reactivity, and improved sleep, all of which influence vasomotor symptom expression. Intensive aerobic exercise and heavy strength training can temporarily trigger hot flashes in some women, particularly during and immediately after the session. Yoga, with its emphasis on breath regulation and parasympathetic activation, tends to be better tolerated by women whose hot flashes are exacerbated by exertion.
Mental Health and Mood: Both Are Effective
Both strength training and yoga show meaningful benefits for mood, anxiety, and depression in midlife women. Resistance training increases circulating BDNF, serotonin precursors, and endorphins, and the sense of physical capability that builds over weeks of training can be profoundly good for self-esteem and identity during a period when the body is changing significantly. Yoga supports mental health through breath regulation, mindfulness, and the parasympathetic nervous system response, which can reduce cortisol and improve emotional resilience. For anxiety specifically, yoga practices with a breath and meditation emphasis may have an edge. For low mood and reduced motivation, the active accomplishment of progressive strength training can be especially helpful.
Muscle Preservation: Strength Training Is Essential
Sarcopenia, the loss of muscle mass with age, accelerates after estrogen declines. Muscle is metabolically active tissue that supports insulin sensitivity, physical function, fall prevention, and metabolic rate. Yoga does not provide a sufficient stimulus to prevent or reverse muscle loss in perimenopause. Resistance training, particularly when combined with adequate protein intake, directly signals muscle protein synthesis and counteracts the anabolic resistance that increases with age. Women who do only yoga are at risk of gradual muscle decline that will compound over the following decades. Incorporating strength work even twice a week makes a meaningful difference to long-term functional health.
Flexibility, Mobility, and Joint Health
This is where yoga offers clear advantages. Perimenopause brings joint stiffness, muscle tightness, and reduced range of motion for many women, partly due to declining estrogen's role in connective tissue hydration and partly due to cumulative lifestyle patterns. Regular yoga practice improves flexibility, hip mobility, shoulder mobility, and spinal health in ways that resistance training alone does not replicate. Good mobility also supports resistance training performance and reduces injury risk. Yin yoga and restorative yoga in particular can address the connective tissue changes of perimenopause in ways that complement rather than compete with strength work.
Combining Both for the Best Outcome
The most effective approach in perimenopause is to combine both. A practical structure might include two to three resistance training sessions per week targeting all major muscle groups, alongside one to two yoga sessions focused on mobility, breath work, and stress regulation. This covers the bone density, muscle preservation, and metabolic benefits of strength training while also addressing hot flash reduction, flexibility, and nervous system regulation through yoga. Tracking workouts over time helps confirm you are staying consistent. Apps like PeriPlan let you log workouts and track patterns over time, which can help you notice when training volume drops and re-engage before deconditioning sets in. Starting with whatever is most accessible is fine. Adding the second modality once the first is a habit avoids the common pattern of trying to overhaul everything at once and ending up doing nothing consistently.
