How often should I do resistance training after 40?

Adults over 40 should aim for at least two resistance-training sessions per week, targeting all major muscle groups. The WHO and Australian 24-Hour Movement Guidelines set this as the minimum; three sessions per week is optimal for most people in their 40s and 50s. By the 70s, two supervised sessions per week remain the goal — the same frequency, but with more functional exercises, lighter loads, and a falls-prevention overlay. Consistency over years matters far more than any single session's intensity.

What exercises are most important as I age?

Compound multi-joint exercises provide the greatest return across all age groups: squat variations (goblet squat, leg press, box squat), hip hinges (Romanian deadlift, hip thrust), horizontal pressing (push-up, dumbbell bench), vertical pressing (seated overhead press), pulling (seated row, lat pulldown, inverted row), and loaded carries (farmer's walk). These patterns load the hip, spine, and wrist — the three sites most vulnerable to osteoporotic fracture — and build the functional movement required for daily life. Isolation exercises are useful add-ons but should not replace compound lifts.

Is heavy resistance training safe for older adults?

Yes, with appropriate screening and graduated load. The LIFTMOR trial demonstrated that supervised high-intensity resistance training (5 sets × 5 reps at ≥85% of one-rep maximum) in postmenopausal women with osteoporosis improved bone density and physical function without serious adverse events. The key qualifiers are proper screening, trained supervision, and graduated progression. Adults with fragility fractures, severe arthritis, recent surgery, or significant cardiac conditions require referral to an Accredited Exercise Physiologist before commencing heavy training.

What does Medicare cover for exercise physiology?

A GP Chronic Disease Management Plan (MBS item 965, replacing item 721 from July 2025) opens a referral pathway to an Accredited Exercise Physiologist under MBS item 10953, with up to five Allied Health visits combined per calendar year. The Medicare rebate is approximately AUD 61.80 per session. Bulk-billing is rare — confirm with the AEP clinic before booking. Adults over 75 can access a Health Assessment (MBS 705) that includes physical activity and falls-risk review. The ATSI Health Assessment (715) applies from age 55 for Aboriginal and Torres Strait Islander patients.

Will I get sore when I start resistance training?

Delayed-onset muscle soreness — the aching stiffness that peaks 24–72 hours after a novel exercise session — is expected in the first one to two weeks and is not a sign of injury. It attenuates by weeks three and four through the repeated-bout effect. Light movement, adequate protein intake of around 0.4 grams per kilogram of body weight per meal, and sleep are the most effective management strategies. Soreness should not be used as a reason to stop training — it signals that muscles are adapting, which is precisely the goal.

What community programs exist in Australia for older adults?

Strength for Life, run through COTA SA with over 100 venues nationally, is a supervised group resistance-training program for adults over 50, available for AUD 5–10 per session. Heart Foundation Walking offers free national walking groups as a complement to resistance training. Many council leisure centres run structured seniors gym programs at low cost. For people with osteoporosis, Onero (a LIFTMOR-based supervised program) is delivered by trained physiotherapists and accredited exercise physiologists at specialist sites around Australia.

Sarcopenia and age-related muscle loss

Resistance training after 40: AU evidence-based sarcopenia prevention

By Dr HB Lo, FACRRM Reviewed 4 November 2026 12 min read

Sarcopenia — progressive age-related muscle loss — accelerates after 40 and becomes clinically significant by the 60s. Resistance training is the single most evidence-supported intervention to slow and partially reverse this trajectory.

The WHO and Australian Movement Guidelines recommend muscle-strengthening at least twice weekly for all adults. Supervision and dosing change across age bands: a 45-year-old can train heavily with minimal oversight; an 80-year-old needs supervised, functional, falls-aware programming.

Your GP can refer you to an Accredited Exercise Physiologist via a GP Chronic Disease Management Plan, with Medicare rebates available.

Sarcopenia — the progressive loss of skeletal muscle mass, strength, and function with age — is not a disease of old age. It is a process that begins in the 40s and whose consequences are felt decades later. Roughly 0.5–1% of muscle mass is lost per year after 40, with strength declining faster — approximately 3% per year after 60 (Cruz-Jentoft et al., EWGSOP2 2019). The resulting frailty, falls, fractures, metabolic disruption, and functional dependency represent among the most prevalent and costly preventable consequences presenting to Australian general practice.

Resistance training is the single most evidence-supported intervention to slow, halt, and partially reverse this trajectory (Liu and Latham, Cochrane 2009). Dose, exercise selection, and supervision requirements evolve substantially across the lifespan. The goal of this article is to map that evolution — from the 40s masters-athlete window, through the perimenopausal bone-loading priority of the 50s, to the supervised functional programming of the 70s and 80s — and to anchor each decade to the Australian general practice pathway.

A. Core clinical — the AU general-practice framework

Who to screen and when

Sarcopenia is clinically silent through the 40s and much of the 50s. The first visible signs — reduced grip strength, difficulty rising from a chair without arm assistance, unsteady gait — often emerge only when substantial reserve has already been lost. The EWGSOP2 consensus (Cruz-Jentoft 2019) defines sarcopenia by low muscle strength as the primary criterion, confirmed by low muscle quantity or quality, with poor physical performance indicating severity.

In general practice, opportunistic screening at routine consultations for adults over 60 is clinically reasonable:

Sit-to-stand test (30 seconds) — count repetitions; below-normal for age and sex warrants further assessment
Grip strength dynamometer — below 27 kg (men) or 16 kg (women) is the EWGSOP2 threshold for probable sarcopenia
Timed Up and Go (TUG) — above 12 seconds indicates functional limitation
Gait speed — below 0.8 m/s over 4 metres is clinically significant

Routine workup for suspected sarcopenia includes U+E (creatinine baseline before initiating high-volume training or creatine supplementation), 25-OH-vitamin D, ferritin, TSH, HbA1c in metabolic risk patients, and testosterone if male hypogonadism features are present. Bone mineral density by DXA is indicated when osteoporosis risk is elevated — particularly postmenopausal women, men over 70, long-term corticosteroid users, and those with fragility fracture history.

The prescription hierarchy

The WHO 2020 Global Guidelines on Physical Activity and the Australian 24-Hour Movement Guidelines for Older Adults (DoHDA 2026) set the minimum floor: muscle-strengthening activity ≥2 days per week for all adults, with adults aged 65 and over adding multicomponent balance and functional activity at least 3 days per week.

The practical prescription hierarchy for general practice:

Identify and address barriers — cost, gym intimidation, knowledge gaps, joint pain, comorbid conditions limiting participation
Screen for AEP supervision triggers (see Section D) — refer to an Accredited Exercise Physiologist under GPCCMP where criteria are met
Prescribe by age band — dose, exercise selection, and load change materially across the decades
Establish progressive overload — the fundamental mechanism driving adaptation; without it, training stalls
Pair with protein — approximately 0.4 g/kg per meal across four meals daily; total daily intake of 1.2–1.6 g/kg is the target for adults over 50 building or preserving muscle

B. Evidence appraisal — age-band dosing and the load debate

Age-band dosing: the operational specification

Evidence for resistance training in older adults is robust and graded across age groups, with the Cochrane review (Liu and Latham 2009) establishing that progressive resistance training in older adults improves strength, functional capacity, and gait speed. The age-band dosing specification below synthesises the WHO guidelines, ACSM Position Stand (2026), EWGSOP2, and LIFTMOR trial data.

Age 40–49 — build the reserve. This is the masters-athlete window: recovery is robust, training capacity near-peak, and physiological investment now pays dividends through the 60s and 70s. Under-training in this decade drains the reserve drawn upon across later life. Prescription: 2–3 sessions per week, compound lifts across all major movement patterns, 3–4 sets × 6–12 reps at 70–80% of one-rep maximum (1RM), RPE 8 (two reps in reserve). Progressive load increase of 2.5–5% per week is non-negotiable. Deload week every 4–6 weeks prevents accumulated fatigue.

Age 50–59 — same blueprint, smarter recovery. Joint wear begins to emerge; perimenopausal women face accelerated bone and muscle loss driven by oestrogen withdrawal. The core prescription is unchanged but recovery windows expand to 48–72 hours between sessions targeting the same muscle group. For women in this decade, bone-loading priority justifies supervised high-intensity training — the LIFTMOR-style 5 sets × 5 reps at ≥85% 1RM — where screening allows (Watson et al., LIFTMOR 2018). Slower eccentric tempo (3–4 seconds lowering) supports tendon adaptation.

Age 60–69 — machines and dumbbells, moderate loads, balance entry. Adults over 60 retain substantial strength-training adaptability (Cochrane Liu 2009). Prescription: 2–3 sessions per week, 2–3 sets × 8–15 reps at 60–75% 1RM. Machines and dumbbells become the primary tools over barbells. The key addition is balance and loaded carry every session — calf raise, single-leg stance, farmer’s walk. A supervised induction of 6–12 weeks is recommended before unsupervised independent training.

Age 70–79 — supervised, functional, falls-prevention overlay. Sarcopenia prevalence climbs sharply; multimorbidity is common. The World Falls Guidelines 2022 (Montero-Odasso) integrate exercise as a core falls-prevention intervention alongside medication review and home-hazard assessment. Prescription: 2 sessions per week minimum, 1–3 sets × 10–15 reps at 50–70% 1RM, with functional priority — sit-to-stand × 10, step-ups, farmer’s walk 10–20 metres, stair climb, calf raise, row, overhead reach. RPE 7–8 (1–2 reps in reserve). AEP supervision is mandatory for anyone with a falls history, fragility fracture, or significant cardiac or neurological comorbidity.

Age 80+ — chair-based, body-weight, strict falls overlay. Community group programs and in-home AEP via Home Care Package are the primary delivery vehicles. Exercises: seated sit-to-stand × 10 (progress to weighted vest), resistance band row and press, seated marching, ankle circles, chair-supported single-leg stance, hand grip. High-impact training is contraindicated in established osteoporosis (RACGP/HBA 2024).

Does load level matter for hypertrophy?

Schoenfeld et al. (2017) demonstrated in a systematic review and meta-analysis that low load (≤60% 1RM) and high load (>60% 1RM) produce equivalent hypertrophy when sets are taken near failure (RPE 8–9). High load retains a clinically meaningful advantage for pure strength. For older adults with joint pathology limiting high-load training, the equivalence finding is important: effective muscle-building stimulus is achievable at joint-protective loads provided sets are worked near failure. The prescriber’s first priority is ensuring effort (proximity to failure) is adequate — not chasing a specific load percentage.

LIFTMOR: heavy training in osteoporosis?

The LIFTMOR trial (Watson 2018) enrolled 101 postmenopausal women with low bone mass and demonstrated that supervised high-intensity resistance and impact training (5 × 5 at ≥85% 1RM plus landing exercises) produced significant improvements in lumbar spine and femoral neck bone mineral density — without serious adverse events. The LIFTMOR-M (Harding 2020) replicated the finding in men with osteopenia and osteoporosis. The key qualifier is supervised setting: the LIFTMOR protocol is not appropriate for unsupervised gym training in osteoporotic patients. In Australia, trained physiotherapists and AEPs deliver LIFTMOR-based programs through Onero and specialist bone-health clinics.

Neural adaptations precede visible results

Strength gains in the first four weeks of training occur primarily through neural adaptation — improved motor unit recruitment and synchronisation — without measurable hypertrophy (ACSM 2026). This is clinically important when setting expectations: patients who do not see physical change in the first month have not failed to respond. Measurable hypertrophy appears at 6–8 weeks; bone density adaptation requires 6–12 months of consistent load (LIFTMOR 2018).

C. Exercise prescription in practice

The fundamental movement patterns that should anchor any age-appropriate resistance program:

Squat — goblet squat, box squat, leg press, Smith machine squat; leg press is the most accessible and joint-protective option for over-70s
Hip hinge — Romanian deadlift, hip thrust, 45° back extension; hip thrust is favoured for older adults as lumbar demands are lower than conventional deadlift
Horizontal press — push-up progression (kneeling → standard → decline), dumbbell bench press
Vertical press — seated dumbbell overhead press, landmine press (shoulder-friendly), machine shoulder press
Pull — seated cable row, lat pulldown, inverted row, assisted chin-up
Loaded carry — farmer’s walk, suitcase carry, waiter carry; the most underutilised yet functional movement in older-adult programming

One exercise per movement pattern per session covers all major muscle groups and loads the hip, spine, and wrist. For adults in their 40s and 50s, rotating exercise variations maintains stimulus novelty and reduces overuse injury. For adults over 70, consistency and familiarity with a fixed exercise menu are more important than variety.

Progressive overload

Progressive overload — systematically increasing the training demand over time — is the fundamental driver of adaptation. Without it, training becomes maintenance at best and stagnation at worst. The standard approach:

Increase load by 2.5–5% per week until a performance plateau is reached (typically 12–16 weeks for a beginner)
Then introduce microcycles: 4-week waves of light/moderate/heavy/deload, allowing recovery and supercompensation
For adults over 60: extend the initial technical learning phase to 12–16 weeks before significant load progression; movement quality takes absolute precedence

Home and minimal-equipment options

Home-based resistance training is effective when effort is comparable to gym training, with home-based meta-analyses (2019) showing equivalent strength outcomes when supervision is matched. The practical equipment hierarchy: body weight → resistance bands (AUD 15–60) → adjustable dumbbells (AUD 100–400) → kettlebell (AUD 30–100) → suspension trainer (AUD 50–250). Blood-flow restriction (BFR) training at low loads (20–30% 1RM) produces hypertrophy comparable to higher loads in older adults and is a useful option for patients who cannot tolerate heavy loading due to joint pathology — though BFR requires practitioner guidance due to cardiovascular precautions.

D. Australian operations

MBS pathway

A GP Chronic Disease Management Plan (GPCCMP, MBS item 965 — replacing item 721 from July 2025 — with review under item 967) opens a referral pathway to an ESSA-registered Accredited Exercise Physiologist under MBS item 10953, with up to five combined Allied Health visits per calendar year at a rebate of approximately AUD 61.80. Physiotherapy is covered under item 10960 within the same five-visit cap.

Relevant additional MBS items:

75+ Health Assessment (705/707) — includes physical activity review and falls-risk assessment; the most appropriate entry point for previously inactive older adults
45–49 Health Assessment (701) — includes musculoskeletal screen
ATSI Health Assessment (715, from age 55) plus ATSI Allied Health items 81120–81125 (10 visits per calendar year)

Supervision triggers — refer to AEP/physio under GPCCMP

The following patients require ESSA-registered AEP or physiotherapy-supervised induction before independent gym training:

Prior fragility fracture; T-score ≤ −2.5 (osteoporosis); recent surgery within 3 months; severe arthritis limiting range of motion; cardiac comorbidity (recent ACS, NYHA III–IV, uncontrolled arrhythmia, severe aortic stenosis, BNP >100); neurological condition (Parkinson’s disease, stroke, peripheral neuropathy, MS); recurrent falls (≥2 in 12 months); hypertension above 160/100 uncontrolled; HbA1c above 9%; severe COPD (FEV1 below 50%); pregnancy or postpartum within 12 weeks.

Cost benchmarks (AU 2026)

Commercial gym AUD 60–120 per month; council leisure centre seniors gym AUD 30–60 per month; Strength for Life AUD 5–10 per session; AEP appointment AUD 100–180 (rebate approximately AUD 61.80, bulk-billing rare); in-home AEP via Home Care Package bundled under package. Home equipment setup AUD 100–400 once-off for bands plus adjustable dumbbells.

E. Special populations

Perimenopausal and postmenopausal women. The decade of perimenopause brings accelerated bone and muscle loss driven by oestrogen withdrawal. Resistance training with adequate load and impact is the most effective non-pharmacological strategy for preserving both (LIFTMOR Watson 2018; RACGP/HBA 2024). Coordinate with osteoporosis pharmacotherapy where DXA indicates treatment threshold (antiresorptive agents and exercise are complementary, not alternatives).

Type 2 diabetes. Resistance training improves insulin sensitivity independent of weight loss. For insulin-treated patients, glucose monitoring before and after novel training sessions is prudent, particularly until response patterns are established. The GPCCMP opens the AEP referral pathway for type 2 diabetes as a qualifying chronic condition.

Cardiac disease. Resistance training is now supported as safe and beneficial in stable heart failure and post-MI rehabilitation (ACSM 2026). Patients with NYHA III–IV, unstable angina, or significant left ventricular outflow obstruction require cardiologist input before commencing supervised programs.

GLP-1 receptor agonist users. Emerging evidence suggests lean mass loss alongside fat loss in patients on semaglutide and tirzepatide. Resistance training is the primary strategy to preserve lean mass during pharmacological weight loss. Position statements from ACSM and ESSA are anticipated in 2026–27; prescribe resistance training proactively in this group now.

Statin users with myalgia. Clinical trial data shows statin-associated myalgia at approximately 9.4% in RCTs — similar to placebo rates — suggesting a substantial nocebo effect in observational reports (Cai et al. BMJ 2021). Statin use is not a contraindication to resistance training. If true myalgia is documented, trial an alternative statin or dose reduction; do not abandon exercise.

When to escalate

Refer or escalate when:

Suspected or confirmed sarcopenia with functional impairment — refer to AEP under GPCCMP for structured supervised prescription; defer unsupervised gym attendance until induction is complete
Recurrent falls (≥2 in 12 months) — multifactorial falls assessment per World Falls Guidelines 2022; integrate exercise, medication review, and home-hazard assessment
Established osteoporosis with fragility fracture — refer to Onero-trained AEP or physiotherapist for supervised LIFTMOR-style protocol; do not send independently to a commercial gym
Suspected cardiac contraindication — cardiologist or exercise physiologist with cardiac rehabilitation experience before prescription
Parkinson’s disease, stroke, or other neurological condition — neurophysiotherapy or AEP with neurorehabilitation experience
