Question

If you can't take your heart rate, a good way to recognize that you're exercising efficiently is whether or not

A. you're experiencing a little bit of huffing and puffing.
B. it's difficult to have a conversation.
C. you're gasping for breath.
D. your muscles are burning.

Answer 1

A good way to recognize if you're exercising efficiently when you can't take your heart rate is to assess your breathing. If you're huffing and puffing a little bit, it indicates that you're exerting enough effort to improve cardiovascular fitness.

Step-by-step explanation:

A good way to recognize if you're exercising efficiently when you can't take your heart rate is to assess your breathing. If you're experiencing a little bit of huffing and puffing, it indicates that you're exerting enough effort to increase your heart rate and improve cardiovascular fitness. The Talk Test can also be used as a guideline - during moderate-intensity exercise, you should be able to talk, but not sing, whereas during vigorous-intensity exercise, you should only be able to say a few words without pausing for a breath.

Answer 2

I most commonly hear that the answer is B. it's difficult to have a conversation.

The saying goes like this:
If you can sing while you are exercising, you aren't working hard enough.
If you find it hard to sing or can keep up an interrupted conversation, you are working at a good pace.
If you find it hard to breathe, then you are working too hard.
