Circuit training uses a series of exercise stations (which could also include strength training stations), with relatively brief rest intervals between each station. The purpose is to keep the heart rate elevated near the aerobic level for a variety of exercises. Learn more about circuit training.
Cross-training basically means participating in a variety of different forms of aerobic exercise, either within each session (for example, biking for 15 minutes and then running for 15 minutes) or day-to-day (for example, running 2 days a week, cycling 2 days a week, and swimming 1 day a week). It’s a good idea to cross-train to prevent plateaus and overuse injuries and boost your overall fitness level.
