Scuba diving emphasizes controlled movement, breathing, awareness, and light to moderate effort underwater. It is not usually a cardio workout in the traditional sense, but it still involves equipment handling, finning, buoyancy control, and environmental awareness. Conditions, current, depth, and gear can change the physical demand.
