Question

If your heart is not strong enough or efficient enough, it is difficult to

breathe
perspire
lift weights
stretch

Answer 1

The answer would be breathe since the heart pumps oxygen to your lungs

Answer 2

Honestly, if this was a one choice question, the answer would most likely be A. But if this was a multiple choice question, all of them would be correct.

The most likely answer would be A, because if your heart is having a hard time, the lungs will also have a hard time. and in order to perspire, lift weights, and stretch, you will need constant breathing.
