Question

what type of exercise enhances circulation and reduces inflammation in the body?
a. aerobic exercise
b. stretching
c. yoga
d. strength training
what is one primary benefit of low - impact activities?
a. reduces joint strain
b. builds muscle mass
c. regulates cortisol
d. improves focus

Explanation:

First Question:

Aerobic exercise (like running, cycling) increases heart rate, improving blood circulation. It also has anti - inflammatory effects due to improved oxygen delivery and metabolic processes. Stretching mainly improves flexibility, yoga has multiple benefits but not primarily for circulation/inflammation in the same way as aerobic, and strength training builds muscle. So aerobic exercise is the answer.

Low - impact activities (e.g., swimming, walking) put less stress on joints. Building muscle mass is more from strength training, regulating cortisol is related to stress management and not a primary low - impact benefit, and improving focus is more mental. So reducing joint strain is the main benefit.

Answer:

a. Aerobic exercise
