Cardio plus weights beats any single workout for blood pressure in sedentary adults

Sitting for most of the day has become the default in modern life, and sedentary behaviour is linked with a long list of chronic diseases. Exercise is the standard prescription, but 'exercise' covers everything from Tai Chi to high-intensity intervals, and a sedentary adult trying to improve blood pressure, cholesterol or blood sugar gets little guidance on which type serves which goal. Individual trials usually compare one programme against a control group, not against each other. A network meta-analysis can rank many programmes at once by combining direct and indirect comparisons, which is exactly what this study set out to do.

The authors searched four major databases for randomised controlled trials in sedentary adults published up to November 2024. Forty-seven studies with 2,355 participants qualified. Programmes including aerobic training, strength and resistance work, their combinations, HIIT, Pilates, Tai Chi and functional training were compared in a network meta-analysis covering blood pressure, blood lipids and blood glucose measures. Each programme was then ranked by its probability of being the most effective option for each outcome, and the risk of bias in every trial was formally assessed.

Combined programmes pairing aerobic work with strength or resistance training were significantly better than any single exercise type at lowering both systolic and diastolic blood pressure. Pilates ranked first for systolic pressure specifically, HIIT led for reducing total cholesterol, and the aerobic plus strength combination had the clearest advantage for raising HDL cholesterol. Tai Chi topped the rankings for LDL cholesterol and for glycated haemoglobin, the long-term blood sugar marker, while Pilates and functional training ranked best for glucose and the aerobic plus resistance pairing ranked best for insulin. Some 85% of the included studies were judged at low risk of bias, and the funnel plot showed no significant publication bias.

The headline message complicates the idea of a single best exercise: the top of the leaderboard changes depending on which health marker you care about. That said, network rankings lean partly on indirect comparisons between trials that never faced each other, so a first-place probability is weaker evidence than a head-to-head win. The finding that combined aerobic and strength training beats single approaches for blood pressure echoes wider exercise research, while the strong showings for Tai Chi and Pilates on metabolic markers are more surprising and deserve direct confirmation. How intensity, session length and adherence shaped these rankings remains an open question.

For a sedentary adult starting to train, this is a reason to think in terms of goals rather than hunting for one universally best workout. If blood pressure is the concern, the evidence here favours mixing aerobic exercise with strength work over doing either alone. If cholesterol or long-term blood sugar is the target, interval training and Tai Chi respectively made the strongest showing in these rankings. The broader point is encouraging: across 47 trials, many quite different forms of exercise moved meaningful health markers in people who had been sedentary.
