This randomized controlled trial aims to investigate the comparative effects of nature-based versus indoor exercise interventions on cognitive performance, psychological well-being, and physiological stress in Malaysian adults.

The study will examine changes in attention, working memory, affect, blood pressure, body composition, and salivary cortisol across baseline, mid-point, and post-intervention assessments.
