Question

In contrast, an exercise that involves the use of more than one major muscle group at a time is called a ________exercise.

A) Isolation
B) Concentric
C) Eccentric
D) Compound

Answer 1

Answer: D) Compound

Step-by-step explanation:

Compound exercises are exercises that work multiple muscle groups at the same time.

Isolation refers to "isolating" a single muscle

Concentric refers to the portion of an exercise that shortens the muscle.

For example the initial part of a bicep curl where the weight is being brought up is the concentric portion of the movement.

Eccentric refers to the portion of that exercise where the muscle is lengthening.

For example the latter part of a bicep curl where the weight is being let down and the bicep is lengthening
