Why women deserve more
from strength training.

“Lift weights” is familiar advice. “Lift heavy” is increasingly familiar too. But between hearing that message and feeling able to act on it sits a much more interesting question: what helps a woman build strength she can use and keep building over time?

That question connects several strands of my work: resistance training in midlife women, the experience of exercise, and the physiology behind strength. It also exposes a problem with reducing training to a single instruction—or reducing ageing muscle to a single measurement.

What the research has—and hasn’t—asked

Our scoping review mapped resistance-training research in healthy midlife women. Strength and body composition dominated the outcomes. Cohorts were mainly postmenopausal and often described as untrained, inactive or sedentary; perimenopausal and resistance-trained women were less represented. Moderate loading appeared frequently, while heavier prescriptions received less attention [1].

Those details change how we read a headline. Results from someone beginning resistance training do not automatically answer what an experienced lifter needs next. “Inactive” and “untrained” are not interchangeable either: a woman might run regularly but have little experience of lifting.

There is another distinction worth making. Finding fewer heavy-load programmes in research does not show that women in gyms are choosing to avoid them. It does not prove that moderate loading was inadequate. Our review maps what has been studied; it does not rank programmes by effectiveness or establish a universal prescription [1].

Why “just lift heavier” misses something

Before asking someone to add weight, it helps to understand what makes training possible for her.

In the WISH project, interviews with 24 UK women already doing muscle-strengthening exercise identified barriers including time, access, confidence and social perceptions. Support, choice and useful information helped. The study examined participation broadly, rather than avoidance of heavy loads specifically, but it shows why participation cannot be reduced to motivation alone [2].

For coaching, that suggests practical questions. Does she know how to set up the equipment? Can she ask for help without feeling judged? Is the session manageable around work and caring responsibilities? Does she understand what progression is meant to achieve?

My approach is to make the next step clear and achievable, then build from it. A heavier weight becomes more useful when the person understands the movement and feels able to return for the next session.

Heavy should be an option, not an age limit

Tøien and colleagues’ review makes a case for heavy and very heavy strength training in older adults, highlighting strength gains and neural adaptations. It challenges the idea that ageing should automatically mean keeping every exercise light [3].

“Heavy” is relative to the person’s capacity in a particular exercise. It is not a fixed number of kilograms. The paper discusses loading around 80% of one-repetition maximum and above; that description is not an instruction to begin there. A review supporting heavier training is also not proof that it is the best choice for every person, exercise or goal [3].

The NSCA position statement for older adults emphasises individualised, progressive resistance training [4]. In practice, I would consider movement skill, health, symptoms, training history and recovery before deciding what load makes sense. Age alone should not close the door to a meaningful challenge.

Muscle quality alone is not enough

Muscle size is an incomplete explanation of what someone can do. “Muscle quality” tries to capture more of the picture, but the term has different meanings. It can describe force relative to muscle size, or characteristics of tissue composition and structure. Those measures should not be treated as interchangeable [5].

A strength-to-size ratio can be informative, but it does not isolate the muscle from the rest of the person. Its meaning depends on the strength test and the measure of size. It cannot, by itself, identify all the processes responsible for weakness.

This is the important limit: replacing “more muscle” with “better-quality muscle” still leaves us asking what is being measured and whether it explains the outcome we care about. Orssatto and colleagues argue that muscle mass and intrinsic muscle quality account for an important but incomplete part of age-related losses in strength and mobility [6].

Strength belongs to a whole motor system

Orssatto and colleagues propose reframing sarcopenia through the ageing motor system: the brain, spinal cord, peripheral nerves, neuromuscular connections and muscle. It widens the explanation beyond the tissue producing the force. This is a conceptual framework, rather than a new diagnostic standard [6].

The distinction between size and function is already important clinically. The European EWGSOP2 consensus uses low strength to identify probable sarcopenia; low muscle quantity or quality confirms it, while poor physical performance indicates severe sarcopenia [7]. These are clinical criteria, not a diagnosis to make from a gym body-composition scale.

For training, the implication is to measure the outcome directly where possible. If the goal is getting out of a chair, climbing steps or carrying shopping, a body-composition result alone cannot show whether those tasks improved. Strength, power and everyday performance answer related but different questions.

What this means for your training

Our review also found less attention to several perceptual, psychological and implementation outcomes than to strength and body composition [1]. Physical changes matter, but they do not fully describe someone’s experience of a programme.

My practical interpretation is to keep four things in view:

• A relevant starting point. Consider your recent training, movement skills, health and goals rather than relying on your age or a beginner/experienced label.
• A clear progression. Choose a challenge you can perform with appropriate control, then review when and how to progress it.
• More than one outcome. Track strength and the tasks that matter to you; interpret body measurements in that context.
• The experience of training. Discuss effort, discomfort, recovery and whether the programme fits your week. Use those answers alongside performance to guide adjustments.

Heavier training can be part of that process. So can learning a movement, rebuilding consistency or adjusting a session when circumstances change. The useful question is what challenge helps this person move forward, and what support makes it possible to continue.
