Fact-check status: passed

The following claims were verified through Perplexity Sonar before the questions were finalised. The host can reference any of them during play:

• The FITT principle stands for frequency, intensity, time, and type, which are key factors used to design an effective exercise program.
• The CDC recommends that adults aim for at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week.
• In addition to aerobic activity, the CDC recommends that adults perform muscle-strengthening activities targeting all major muscle groups at least two days per week.
• Aerobic exercise uses oxygen to meet the body's energy demands during sustained activity, while anaerobic exercise involves short bursts of high-intensity effort that do not rely on oxygen.
• Muscular endurance is defined as the ability of a muscle or group of muscles to exert force against resistance consistently and repetitively over a period of time.
• Flexibility is the ability of a joint or series of joints to move through an unrestricted, pain-free range of motion.
• The primary purpose of a warm-up before exercise is to gradually increase heart rate, blood flow, and muscle temperature to prepare the body for more vigorous activity and reduce injury risk.
• A cool-down after exercise helps the body transition from an elevated state back to rest by gradually lowering heart rate and blood pressure to prevent dizziness or fainting.
• Proper hydration during exercise is essential to replace fluids lost through sweat, which helps maintain body temperature, heart function, and physical performance.
• Static stretching is a type of flexibility training that involves moving a joint until a stretch is felt and holding the position, typically for 15 to 60 seconds.
