This randomized controlled trial investigates the effects of two types of stair-climbing exercise snacks versus moderate-intensity continuous training on vascular health, body composition, and blood lipids in overweight or obese adults. Participants will be assigned to one of four groups for 6-8 weeks. The control group receives no exercise intervention. Primary outcomes include endothelial function (ultrasound), body composition (InBody), and lipid profile (blood test).
