what is a common benefit of hiit?1 pointincreased flexibilityburns a lot of calories in a short timereduces muscle strengthrequires no physical exertionsuper setting is especially beneficial for:1 pointimproving sleep qualitysaving time by working opposing muscle groupsincreasing meditation skillsenhancing cardiovascular endurance

Explanation:

• For the first question: HIIT (High - Intensity Interval Training) is known for its high - intensity nature. During the short bursts of intense activity in HIIT, the body burns a large number of calories. Flexibility is more associated with stretching exercises. HIIT is not known to reduce muscle strength; in fact, it can contribute to muscle endurance and sometimes strength (depending on the exercises). And HIIT definitely requires physical exertion.
• For the second question: Super Setting involves performing two exercises back - to - back with little or no rest. When working opposing muscle groups (e.g., biceps and triceps), it can save time as you don't have to wait for a muscle group to recover as much. Sleep quality is more related to overall lifestyle and sleep - hygiene. Meditation skills are separate from weight - training techniques like super setting. Cardiovascular endurance is more related to activities like running, cycling, etc., rather than super setting which is more of a strength - training technique.

Answer:

• First question: Burns a lot of calories in a short time
• Second question: Saving time by working opposing muscle groups
