Motherhood, Bone Loss, and Why Strength Training Is Non Negotiable
Motherhood changes the body in profound ways far beyond what we see on the surface.
Pregnancy, breastfeeding, sleep deprivation, and prolonged periods of physical and emotional stress all place real demands on a woman’s skeletal system. Yet bone health is rarely discussed when we talk about postnatal recovery or long term maternal health.
It should be.
Does motherhood affect bone density
Yes and the science is clear. During pregnancy and breastfeeding, a mother’s body prioritises calcium transfer to support fetal and infant development. Studies show that women can experience temporary bone mineral density loss particularly in the spine and hips during these stages. While some bone density is naturally restored after weaning, not all bone loss is fully recovered especially if pregnancies are close together, breastfeeding is prolonged, nutrition or sleep are compromised, or strength training is not part of regular movement.
Over time this can compound particularly as women move into perimenopause when estrogen a key protector of bone mass begins to decline. This is why mothers are at a higher long term risk of bone density loss if strength training is neglected.
Why strength training matters for mothers’ bone health
Bones need load to stay strong. Weight bearing and resistance-based strength training sends a clear signal to the body that this structure is needed and should be maintained. Research consistently shows that strength training stimulates bone remodelling, helps preserve bone mineral density, improves joint stability and posture, and reduces the risk of fractures later in life.
For mothers this is not about training intensely or aggressively. It is about regular progressive loading that supports the skeleton while respecting recovery. Strength training becomes a form of preventive healthcare.
The hidden cost of just staying active
Many mothers stay active by walking, chasing children, or doing cardio but still avoid strength training. While movement is beneficial, low load activity alone is not enough to protect bone mass. Without resistance muscle mass gradually declines, bones receive less mechanical stimulus, postural weakness and joint pain increase, and injury risk rises over time.
This is why strength training deserves priority not as an extra but as a foundational practice for maternal health.
Strength training also supports the realities of motherhood
Beyond bone health strength training helps mothers carry children and daily loads more safely, improve posture after years of lifting and bending, reduce back hip and shoulder pain, build energy resilience under chronic stress, and feel capable in bodies that have changed.
This is not about getting your body back. It is about building a body that supports your life now.
How Infemniti supports mothers on this journey
At Infemniti we understand that motherhood does not come with unlimited time energy or recovery capacity. That is why our approach to strength training for mothers is thoughtful not extreme, progressive not punishing, and flexible not rigid.
We prioritise bone supportive strength training, intelligent load progression, calm women only environments, coaching that adapts to fatigue stress and life demands, and options for personal training or group fitness that fit real schedules. Whether you are newly postpartum, years into motherhood, or navigating perimenopause strength training can and should meet you where you are.
Strength is a long term investment for mothers
Motherhood often teaches women to put themselves last. But protecting your bone health strength and mobility is not selfish. It is essential. Strength training helps mothers stay active and independent longer, reduce injury risk, support healthy ageing, and model strength and self-care to their children.
At Infemniti we believe strong mothers build strong futures for themselves and the families who rely on them.
