How to Protect Your Muscle as You Age: What Actually Helps

Wellorious Editorial

Changes in muscle don’t always announce themselves in the mirror. You
may notice them first when a heavy bag feels harder to carry, getting up
from the floor takes more effort, or stairs demand more from your legs
than they used to.

Muscle mass and strength tend to decline as we get older, although
the pace varies considerably from person to person. Physical activity,
illness, nutrition and periods of inactivity all influence what happens
along the way.

That gives us something useful to work with. Ageing affects muscle,
but muscle continues to respond to training. Regular resistance
exercise, supported by adequate nutrition, can help preserve the
strength and physical capacity we use in everyday life. That’s a much
more useful goal than simply trying to maintain a particular amount of
muscle on a scan.

Muscle mass is only part
of the story

Age-related muscle loss is sometimes described as if everyone begins
losing a predictable percentage of muscle after a certain birthday.
Human ageing is considerably more variable, and strength and muscle mass
can change differently.

One large longitudinal study followed 1,880 older adults for three
years. Leg strength declined roughly three times faster than leg lean
mass, and some participants who maintained or gained lean mass still
lost strength.

That finding helps explain why a body-composition number tells only
part of the story. Muscle tissue matters, of course, but so does the
nervous system’s ability to recruit it and the strength and function
that result.

For everyday life, those differences become tangible. Carrying
groceries, lifting something from the floor, climbing stairs and getting
out of a chair all depend on physical capacity, rather than muscle size
alone. Protecting muscle as we age therefore makes most sense when we
think about three related outcomes: muscle, strength and
function.

Older muscle still
responds to training

One of the more encouraging findings in ageing research is that older
muscle retains the capacity to adapt to resistance exercise.

A 2024 systematic review and meta-analysis of resistance training in
adults aged 65 and older found increases in whole-muscle size and
muscle-fiber area. Leg lean mass measured using body-composition
techniques did not change significantly in the same analysis.

Those results are a useful reminder that different measurements
capture different things. An estimate of lean mass from a
body-composition scan and a direct measure of muscle size are related,
but they capture adaptation differently and shouldn’t be assumed to move
together.

A much larger 2025 network meta-analysis, covering 151 randomized
trials and 6,306 adults aged 60 and older, found improvements across
outcomes that included strength, muscle-related measures and physical
function. Relatively low training volumes performed well for several
outcomes, while moderate or higher volumes tended to be more useful when
maximizing strength was the goal.

Most of those findings came from relatively healthy older adults.
Someone who is frail or substantially physically impaired may respond
differently and may need a more individualized approach.

Together, these studies point in the same direction: resistance
training remains useful later in life.

There is much more to say about how much muscle people can build as
they get older, and the answer depends on factors such as training
history, program design and individual response. We examine that
question separately in Can You Still Build Muscle After 50? What
the Research Actually Shows. Here, the focus is on keeping
existing muscle challenged and capable.

Muscle needs resistance

Walking and other aerobic activity contribute enormously to health,
but maintaining strength requires muscles to work against
resistance.

That resistance can come from dumbbells, kettlebells, resistance
bands, weight machines or bodyweight exercises. What matters is whether
the movement asks enough of the muscles to challenge their current
capacity and whether that challenge can develop over time.

The American College of Sports Medicine’s 2026 position stand, which
reviewed a large body of resistance-training evidence, concluded that
resistance training improves strength and hypertrophy as well as aspects
of physical performance. The evidence also supports more than one
workable approach to training.

For someone starting at home, this leaves plenty of options. Useful
resistance training can be done without specialized equipment or a gym
membership. A few well-chosen movements can cover a great deal: sitting
down and standing up or squatting, pushing, pulling, hinging at the hips
and carrying a load are examples. The appropriate exercise will depend
on your current ability, mobility, experience and equipment.

Start with something you
can repeat

Detailed debates about the ideal number of sets, repetitions and
training days become more relevant when someone is trying to optimize
strength or muscle growth. A person who currently does no resistance
training has a simpler first problem to solve: establishing regular
exposure to it.

The World Health Organization recommends muscle-strengthening
activity involving the major muscle groups on at least two days per week
for older adults. Its broader older-adult guidance also recommends
multicomponent activity emphasizing functional balance and strength on
three or more days per week to help maintain functional capacity and
reduce fall risk.

These are public-health recommendations for populations, so
individual programs can reasonably differ according to health,
experience, goals and capacity.

Research also suggests that relatively modest resistance-training
volumes can produce useful adaptations in older adults. That makes
consistency a sensible early priority. A manageable program performed
regularly is more useful than an elaborate one that quickly becomes
impractical.

Let the exercises grow with
you

An exercise that challenges you today may feel routine several months
from now. That change is a sign of adaptation, and eventually the
training needs to respond.

Progression can take several forms. You might use a little more
resistance, perform another repetition, improve your control, work
through a greater comfortable range of motion or move to a more
demanding version of an exercise. There is no requirement to add weight
every session; progression happens over time, and the appropriate pace
differs between people.

This is one reason general activity and resistance training shouldn’t
be treated as identical. Familiar everyday activities may continue to be
excellent for movement and health while providing progressively less
challenge to muscles that have already adapted to them.

Where protein fits

Resistance exercise creates a demand for adaptation. Nutrition
provides some of the raw material needed to support it, with dietary
protein supplying amino acids used in muscle-protein turnover.

Several expert groups have recommended somewhat higher protein
intakes for older adults than the minimum intake commonly used for
younger populations. ESPEN and PROT-AGE, for example, recommend around
1.0–1.2 grams of protein per kilogram of body weight per day for
healthy adults over 65, with requirements varying according to
health, activity and nutritional status. That range is best understood
as an expert recommendation for a defined population; individual
requirements can differ.

Research on adding protein supplementation to resistance training
provides useful perspective. Reviews suggest that supplementation can
add a modest benefit to lean or muscle mass in some older populations,
while additional improvements in strength have been less consistent.

In practice, the training stimulus and nutrition work together. For
someone whose normal diet already supplies enough protein, buying a
supplement may add far less value than establishing regular resistance
training. Food preferences, appetite, total diet and health also
matter.

Anyone with kidney disease or another condition that affects protein
requirements should discuss an appropriate intake with a healthcare
professional before adopting a higher-protein target from general health
guidance.

When muscle loss
deserves medical attention

Gradual changes associated with ageing are different from clinically
significant deterioration in muscle, strength or function. Sarcopenia,
for example, is a clinical condition that requires proper assessment; a
consumer body-composition scale or a subjective feeling of being weaker
cannot diagnose it.

Unexplained or rapidly progressing weakness, substantial
unintentional weight loss, repeated falls or increasing difficulty with
ordinary activities are good reasons to speak with a healthcare
professional.

Medical conditions, significant pain, recent surgery or serious
balance problems can also change how resistance exercise should be
approached. In those circumstances, professional guidance can help
identify a suitable way to train while accounting for those
limitations.

A practical way to begin

Someone who currently does little resistance exercise can begin
without an elaborate program. Choose a small number of movements that
collectively challenge the major muscle groups. Use resistance that
requires effort while still allowing you to move with control, allow
recovery between sessions, and return to the exercises consistently
enough to become familiar with them.

Over the following weeks, pay attention to what changes. If an
exercise becomes comfortably easy, increase the challenge gradually. If
a movement consistently causes pain or feels unsafe, adjust it or seek
appropriate guidance rather than pushing through.

Nutrition can be kept equally practical. Regular meals containing
useful protein sources will matter more to most people than chasing the
perfect supplement or timing strategy.

During these first weeks, concentrate on establishing a form of
strength training that challenges you appropriately and fits well enough
into your life to continue.

The bottom line

Ageing affects muscle, strength and physical function, but these
changes are influenced by more than age alone.

Resistance training is one of the best-supported tools we have for
maintaining muscular capacity later in life. It can be done with
different types of equipment and doesn’t require an advanced program to
begin. As strength improves, gradually increasing the challenge gives
the muscles a continuing reason to adapt.

Adequate protein and overall nutrition support that process, while
individual health and physical limitations help determine what training
and dietary approach is appropriate.

Over time, the benefits show up in places that matter: lifting,
carrying, climbing, getting up and continuing to move through daily life
with strength you can use.
