The most accurate statement Deven can make in his description is: "Aerobic exercise can last continuously."
Aerobic exercise is characterized by sustained, moderate-intensity activities that can be performed for extended periods, such as running, swimming, or cycling. While it is true that anaerobic exercises, which involve short bursts of high-intensity effort, often burn more calories in a shorter timeframe due to their intensity, aerobic exercise is specifically designed for endurance and can be performed continuously over longer durations.
