So this is more advice rather than homework help but I’m confused as to what this is asking. Is this referring to an actual workout routine like “jumping jacks+ squats +lunges”or by workout it just means a bike ride (just one activity)

Either.

Explanation:

Aerobic and anaerobic are the two exercise categories. Basically meaning you can choose any exercise that you'd like to do for the assignment. If you want to do a routine with multiple, go for it. But if you want to just one activity for your workout, that's fine as well.

it's false.

"every person has their limitations which prevent us from accomplishing something. some are better than mathematics for example and some are worse. those people who are worse might never be able to become mathematicians, but that does not mean that they would not be great at doing something else."
