Question

Which of the following is an assumption required by the argument that when exercising the muscles in one's back, it is important to maintain a healthy back and exercise the muscles on opposite sides of the spine equally?

1) Balanced muscle development is not necessary for a healthy back.
2) The muscles on opposite sides of the spine do not need to pull equally in opposition directions.
3) Exercising the muscles on one side of the spine is sufficient for maintaining a healthy back.
4) The back does not need to be in proper alignment to protect the spine.

Answer 1

It is important to exercise the muscles on opposite sides of the spine equally to maintain a healthy back.

Step-by-step explanation:

The assumption required by the argument that when exercising the muscles in one's back, it is important to maintain a healthy back and exercise the muscles on opposite sides of the spine equally is that exercising the muscles on one side of the spine is not sufficient for maintaining a healthy back.

When exercising the muscles in the back, it is crucial to work on both sides of the spine equally to maintain balance and prevent muscle imbalances. By working both sides equally, it helps to strengthen the muscles and maintain proper alignment and posture, which is essential for protecting the spine.

Additionally, focusing on balanced muscle development is important for a healthy back since imbalances can lead to strain, fatigue, and potential injuries.
