What are cardiovascular endurance and muscular strength?

Fitness: CV endurance refers to aerobic conditioning, or the body's ability to maintain a heightened level of physical activity over a long period of time. I liken it to marathons over sprints, like driving freeway miles instead of city miles. Your heart is fondest of freeway miles vs short bursts that we think of as city miles-like your auto! Achieve CV endurance by steady exertion over longer pds of time
