Circuit Resistance Training May Lower Blood Pressure After 60

Circuit-based resistance training may help older adults lower blood pressure while building strength. A 2025 systematic review and meta-analysis of 18 randomized trials found that, across 14 trials included in its quantitative analyses, the program reduced systolic blood pressure by 6.1 mmHg, diastolic blood pressure by 2.9 mmHg, and brachial-ankle pulse wave velocity by 102 cm/s versus no-exercise controls. Those are useful changes on measurements that matter for cardiovascular risk, but they do not prove that circuit training beats conventional lifting, walking, or medication.

The results make circuit training worth considering for community-dwelling adults age 60 and older, especially those who want resistance exercise with a more continuous cardiovascular demand. The evidence supports adding it to an inactive routine. It does not yet support crowning it the best exercise format for blood pressure or arterial stiffness.

What the meta-analysis found

Hu et al.'s 2025 systematic review and meta-analysis examined circuit-based resistance training in community-dwelling older adults. The review included 18 randomized controlled trials, with 14 contributing to quantitative analyses. Compared with no exercise, circuit-based resistance training produced pooled reductions of 6.1 mmHg in systolic blood pressure and 2.9 mmHg in diastolic blood pressure.

The review also found a 102 cm/s reduction in brachial-ankle pulse wave velocity, or baPWV. Pulse wave velocity estimates how quickly a pressure wave moves through the arteries; higher values generally indicate stiffer arteries. Arterial stiffening contributes to the rise in systolic blood pressure that becomes common with age. A lower baPWV is therefore encouraging, though it remains a surrogate measure rather than proof that training prevented heart attacks, strokes, or death.

The authors reported that programs performed more than three times weekly had larger systolic blood-pressure reductions. Treat that as a lead, not a prescription written in stone. Individual outcomes included no more than six studies, too few for the authors to assess small-study effects with funnel plots or Egger's test under standard Cochrane criteria. The published information available here also does not provide confidence intervals or heterogeneity statistics for the pooled blood-pressure and baPWV estimates, so readers cannot judge their precision or consistency across trials.

Why the circuit format might matter

Circuit-based resistance training places resistance exercises into a more continuous session structure than a conventional set-and-rest approach. That design may create a cardiovascular stimulus alongside the muscular one. Hu et al. proposed that the format could help explain the vascular findings, but the older-adult trials did not directly measure cardiac output, peripheral vascular resistance, endothelial shear stress, or nitric-oxide activity during circuit sessions.

Related studies make the biological explanation plausible without proving it. In adults with elevated blood pressure or stage-1 hypertension, a 2023 review by Banks et al. found that resistance exercise lowered blood pressure and improved vascular endothelial function. The authors linked those changes to greater nitric-oxide bioavailability and lower peripheral vascular resistance. That evidence concerns resistance exercise broadly, not circuit training specifically.

Other formats with both cardiovascular and resistance elements have produced vascular improvements in different populations. A six-week trial in hypertensive adults found that concurrent HIIT plus resistance training improved flow-mediated dilation and reduced pulse wave velocity, with few non-responders, in Alvarez et al.'s 2024 study. In prehypertensive offspring of people with hypertension, combined aerobic and resistance training improved arterial stiffness, and the improvement correlated with changes in heart-rate variability in a 2023 randomized trial. These studies support the general idea that mixed exercise demands can affect vascular measures. Their participants and protocols were not the same as older adults doing circuit-based resistance training.

Strength and body composition: promising, but less quantified

Hu et al. listed percentage body fat, fat mass, and lean body mass among the primary outcomes. The available publication text does not provide recoverable pooled effect estimates, confidence intervals, or heterogeneity statistics for those body-composition outcomes. It would be a mistake to attach a numerical fat-loss or lean-mass claim to this review without those results.

A smaller intervention offers some relevant context. In elderly obese women with sarcopenia, Jung et al. reported in 2024 that circuit training reduced cardiovascular risk factors and vascular inflammatory markers, with no serious adverse events. That is reassuring for a higher-risk older subgroup, but it does not establish a complete safety profile or prove the same results in all older adults.

Evidence from younger groups should stay in its lane. Circuit training in obese adult men reduced oxidative-stress markers and improved nitric-oxide bioavailability and arterial-health measures in a 2025 study by Son et al.. The findings fit the proposed vascular pathway, but they are not direct evidence that the same mechanism caused the blood-pressure and baPWV changes in older adults.

The comparison that the trials did not make

The central limitation is simple: the quantitative trials in Hu et al.'s analysis used no-exercise control groups. They did not directly compare circuit-based resistance training with conventional resistance training, aerobic exercise, or concurrent training. Therefore, the review can show that circuit training outperformed doing no structured exercise in these trials. It cannot quantify an advantage over other exercise choices.

That distinction matters because resistance training does not produce identical vascular effects under every protocol or in every population. In elderly women, Fujie et al.'s 2024 randomized trial found limited or mixed arterial-stiffness adaptation with traditional resistance training combined with chicken intake. The dietary component makes it hard to isolate training's effect, and the study does not provide a direct numerical comparison with the circuit-training meta-analysis. Still, it fits the possibility that training structure influences vascular outcomes.

Sex and hormonal status may also change the response. A 2025 network meta-analysis in postmenopausal women cautioned against carrying vascular exercise results across populations without attention to hormonal status. Hu et al.'s available results do not provide sex-stratified estimates for blood pressure or baPWV. That leaves uncertainty for postmenopausal women, who make up a large share of the older-adult population.

Studies in young adults reinforce the protocol issue but cannot settle it for older adults. A 2025 study in young obese adults found that resistance exercise could worsen arterial stiffness under some protocols relative to aerobic training. The relevant lesson is not that lifting harms arteries. It is that resistance exercise is a category, not a single exposure; population, intensity, session design, and comparator all matter.

How to use this evidence

For a previously sedentary older adult with elevated blood pressure or arterial stiffness, circuit-based resistance training has credible randomized-trial evidence for improving blood-pressure and baPWV measurements versus no exercise. The estimated 6.1 mmHg systolic reduction is large enough to take seriously, while the missing precision data and lack of active comparators keep the conclusion appropriately narrow.

Circuit-based resistance training looks like a reasonable cardiovascular option within a strength program for older adults. It has not yet earned a claim of superiority over aerobic exercise, conventional resistance training, or a well-designed combined program.

People with hypertension, cardiovascular disease, frailty, or symptoms during exertion should discuss a new program with their clinician or qualified exercise professional. The published evidence does not provide quantitative dropout rates, detailed adverse-event records, or blood-pressure measurements during sessions in frail or hypertensive older adults. A training format can be useful without being a substitute for individual screening, medication management, or follow-up blood-pressure care.
