Strength training for women over 40: what changes and what to lift

What changes after 40, and what lifting does about it

What changes	What the evidence says lifting does	Source
Muscle mass and strength decline, faster through the menopause transition	Resistance training builds muscle in postmenopausal and older women; higher weekly volumes built about 1.3 kg of lean mass vs. about 0.9 kg at lower volumes across 14 trials (low-certainty evidence)	Nunes et al., 2024
Bone density falls as oestrogen drops	Resistance and combined resistance protocols preserve bone mineral density at the lumbar spine and femoral neck in postmenopausal women	Fausto et al., 2023 (umbrella review)
Low bone mass is treated as a reason not to lift heavy	In the LIFTMOR trial, supervised heavy lifting (5 sets of 5 at over 85 percent of 1RM, twice a week for eight months) raised lumbar spine BMD by 2.9 percent vs. a 1.2 percent loss in controls, in women averaging 65 with low bone mass, with one minor adverse event reported under close supervision	Watson et al., 2018
Protein needs rise with age as muscle becomes less responsive to it	Expert consensus recommends at least 1.0–1.2 g/kg/day for older adults and 1.2 g/kg or more for those who train, versus the 0.8 g/kg general RDA	Bauer et al., 2013 (PROT-AGE)
General activity targets	150–300 minutes a week of moderate aerobic activity plus muscle-strengthening on two or more days	WHO

Two things stand out. First, the bone finding: the population most often told to avoid heavy weights is the one in which heavy, supervised lifting had the clearest effect. That does not mean start with a heavy barbell on day one; it means heavy is the destination, not the hazard. Second, the muscle finding: volume matters, and the dose that works is not small. A few light sets with pink dumbbells is better than nothing, but it is not what the trials used.

The plan

The frame is the same as any good personalised routine: full-body sessions, compound movements, progression by rule. The differences for this population are a slower ramp, more attention to the hinge and the loaded carry (hip, spine and grip strength are what prevent the falls and fractures that matter later), and reps kept in the 6–12 range so load is meaningful.

Two days a week (a good start)

Movement	Exercise	Sets × reps
Squat	Goblet squat → leg press or barbell squat	3 × 8–10
Hinge	Romanian deadlift (dumbbell or barbell)	3 × 8–10
Push	Incline dumbbell press or push-up progression	3 × 8–12
Pull	Cable or dumbbell row	3 × 8–12
Carry	Farmer's carry	3 × 30–40 m

Repeat the same session both days, or alternate the squat with a split squat and the row with a pulldown on the second day.

Three days a week (after two or three months)

Keep the same movement pattern per session and alternate exercises: day A barbell squat, RDL, bench press, row; day B leg press, hip thrust, overhead press, pulldown; day C split squat, trap-bar deadlift, incline press, chin-up progression. Carries finish every session. The three-day full-body plan is this structure in full, and the dumbbell-only version covers training at home.

How heavy, and how to progress

Pick a weight where the last two reps of each set are hard but your form does not change; that is one to three reps in reserve. When you complete every prescribed rep in a session, add weight next time: 2.5 kg (5 lb) on upper-body lifts, 5 kg (10 lb) on lower-body lifts, or move to the next dumbbell. If you miss reps two sessions running, drop ten percent and build back. That rule, applied for six months, takes a complete beginner to loads that count as heavy by the LIFTMOR standard. Progressive overload, explained goes deeper.

Recovery takes longer after 40, so a lighter week every fifth or sixth week (same exercises, two thirds of the load) is worth building in from the start rather than waiting for stiffness to force it; see what a deload week is.

Protein, in food

At 1.2–1.6 g per kg, a 68 kg woman is aiming for roughly 80–110 g of protein a day, which is more than most women over 40 eat without planning it. Spread it across three meals of 25–35 g each: eggs or Greek yoghurt at breakfast, a palm of chicken, fish or tofu at lunch and dinner, and the rest from dairy, legumes or a shake. The protein guide has the food lists.

Where a coach fits

The reason women over 40 stop lifting is rarely injury; it is that nobody is checking. A coach's job in this population is to set the loads so you are neither underloading out of caution nor jumping ahead, to keep protein visible, and to notice when a joint complaint should change the plan.

Bay does that over text, free right now. Tell it your goal, your days, your equipment and anything that hurts (a knee, a shoulder, a back), and it builds the plan from the same rules as above: compound movements, 1–3 reps in reserve, weekly sets per muscle in a band set by your experience, a lighter fifth week once you are past the beginner stage, with the lifts that load the sore joint swapped out and the constraint remembered. Each training morning you get the session with a weight per lift; you log it in a line ("goblet squat 16x10x3"); it progresses by rule. Meals go in the same thread as a sentence or a photo, with protein against your target in the evening recap. Nothing to install, and nothing it does depends on a watch or a wearable.
