PubMed, Web of Science, the Cochrane Library, and EBSCO SPORTDiscus were searched from inception to 31 May 2025, supplemented by Google Scholar and reference screening. Eligible interventions lasted at least 4 weeks and were classified as continuous endurance training (CET), resistance training (RT), interval training (INT), combined aerobic-resistance training (CT), or hybrid\/mixed-modality programs (HYB). The primary outcome was flow-mediated dilation (FMD); secondary outcomes were pulse wave velocity (PWV) and carotid intima-media thickness (CIMT). Risk of bias was assessed using RoB 2 and certainty using CINeMA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Fifty-one randomized trials (2,638 participants) were included. Exercise improved FMD (standardized mean difference [SMD], 0.99; 95% CI, 0.69 to 1.29), reduced PWV (SMD, -0.31; 95% CI, -0.44 to -0.18), and reduced CIMT (SMD, -0.20; 95% CI, -0.36 to -0.05). In descriptive treatment-versus-control rankings, HYB had the largest FMD estimate, INT had the largest PWV reduction, and CET\/CT had the largest CIMT reductions; however, these rankings were imprecise and certainty was low. FMD showed substantial heterogeneity (I2\u00a0=\u00a087.1%). Sensitivity analyses excluding high-risk-of-bias studies and specialized cardiac or renal populations did not materially change the direction of findings.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Exercise interventions are associated with favorable vascular changes in adults with overweight or obesity.
