Strength training for women over 50: the case for lifting heavy

Strength training for women over 50 is the intervention with the strongest evidence and the smallest uptake. Most of us were raised on cardio, on shrinking, on the idea that lifting anything heavy would make us bulky. That advice has aged badly. What the research now shows, consistently, is that resistance training preserves the two things that determine whether your seventies are independent or not: muscle and bone.

What happens without it

From around the age of thirty, adults lose muscle mass steadily, and the rate accelerates after fifty. Bone density falls sharply in the years around menopause as oestrogen drops, with women commonly losing a significant percentage of bone mass in the first years after their last period. One in two women over fifty in the UK will break a bone because of osteoporosis, according to the Royal Osteoporosis Society.

Muscle is not vanity. Muscle is how you get off the floor, carry a grandchild, catch yourself when you trip, and recover from illness. Grip strength is one of the better predictors of healthy ageing we have. It is also, unlike many risk factors, directly trainable at any age.

The evidence for lifting after menopause

Two things matter for bones: load and impact. Trials of progressive resistance and impact training in postmenopausal women, including the well known LIFTMOR trial in Australia, found that a short twice weekly programme of heavy resistance work and impact loading improved bone mineral density at the spine and hip in women with low bone mass, with a very good safety record under supervision.

Resistance training also improves insulin sensitivity, blood pressure, sleep quality, mood and, in several menopause studies, the frequency of hot flushes. It is, unusually, a treatment with a long list of side effects that are all good.

How to start if you have never lifted

Two sessions a week. Forty minutes. Six movement patterns. That is the entire programme.

• A squat pattern: bodyweight squat to a chair, progressing to goblet squat.
• A hinge: hip hinge to deadlift. This is the single most useful movement for daily life.
• A push: wall press up, progressing to bench or dumbbell press.
• A pull: seated row or assisted pull down. Essential for posture.
• A carry: walk thirty metres with a heavy weight in each hand. Nothing builds usable strength faster.
• A single leg movement: step ups or split squats, for balance and fall prevention.

How heavy is heavy enough

By the last two repetitions of a set you should genuinely doubt you could do three more. Sets of six to ten repetitions, two or three sets per movement. If you can chat comfortably throughout, the weight is too light to change your bones. Progress the load a little every couple of weeks. That progression is the whole mechanism.

Add impact, and add protein

For bone, load alone is not the full picture. Short bursts of impact help: twenty to fifty small hops or heel drops a few times a week, if your joints and pelvic floor allow. If you have osteoporosis, existing fractures or significant back problems, get a physiotherapist to prescribe this rather than guessing.

And eat enough protein. Older muscle is less responsive to it, so the requirement goes up rather than down. Many nutrition researchers now suggest somewhere around 1.2 grams of protein per kilogram of body weight per day for older adults, spread across meals rather than loaded into dinner. For most women that means adding protein at breakfast, which is where the gap almost always is.

The pelvic floor conversation

If lifting causes leaking, do not stop lifting and do not simply push through it. See a pelvic health physiotherapist. Urinary leaking with effort is extremely common after childbirth and menopause and it responds very well to proper assessment and training. Silently avoiding exercise because of it is how women lose decades of strength.

What to expect, honestly

The first three weeks are the worst and the least rewarding. Strength gains in the first month are mostly neurological, your nervous system learning to recruit muscle, so you will feel more capable before you look different. Visible change takes around twelve weeks. Bone change takes a year and you will never feel it happening at all.

Which is why the framing matters. You are not training for a body. You are training for the woman who carries her own suitcase up the stairs at seventy eight. Two sessions a week. Start with the weight that feels almost embarrassing, and add a little every fortnight.
