If you take one thing away from anything I post, let it be this: heavy strength training is the single most powerful tool you have for ageing well as a woman. More than walking. More than yoga. More than running. More than any supplement. More than any diet.
Lifting weights changes everything that perimenopause and menopause take from you.
Starting around 30, women lose 3–8% of muscle per decade. This loss accelerates significantly in perimenopause because oestrogen plays a direct role in muscle protein synthesis.
As oestrogen drops, your body becomes less efficient at building and holding muscle. Without intervention, by the time many women hit their 60s, they've lost a third of their lean muscle mass. This isn't a vanity issue. Less muscle means slower metabolism, worse insulin sensitivity, weaker bones, more falls and lower independence in the decades ahead.
Bone density follows the same trajectory. Oestrogen is the primary regulator of bone remodelling in women. When it drops, bone breaks down faster than it rebuilds. The first 5–7 years post-menopause are when most bone loss happens. Cardio doesn't put enough mechanical stress on bone to trigger remodelling. Heavy lifting does. Squatting, deadlifting and pressing actually signal your bones to get denser. There is no equivalent.
Then there's the metabolic side. Muscle is your body's biggest glucose sink. Every kilo of muscle you have makes you more insulin sensitive, more metabolically flexible, and less likely to store fat. This is exactly the system that breaks in perimenopause. Building muscle is the most direct fix.
And here's what most women miss: pink dumbbells and bodyweight squats are not enough. You need to lift heavy. The last 2 - 3 reps of your set should be genuinely hard. You need compound lifts such as squats, deadlifts, presses, rows , that use multiple muscle groups. You need to progressively increase the weight over time. Two to four sessions a week, 30 to 45 minutes each. That's it.
