Question

Which of the following statements is the most accurate when discussing strength-training machines?

a. They mimic natural, functional movements.
b. They primarily work the stabilizer muscles.
c. They allow for a full range of motion.
d. They isolate specific muscle groups.

Answer 1

Strength-training machines most accurately isolate specific muscle groups, focusing on primary movers and providing a controlled environment for muscle contraction.

Step-by-step explanation:

Out of the statements provided about strength-training machines, the most accurate is that they isolate specific muscle groups. Unlike functional exercises that mimic everyday movements, strength-training machines often target a specific muscle group, thereby reducing the engagement of stabilizer muscles. Although some machines are designed to allow for a full range of motion, this is not universal, and it also does not necessarily equate to natural or functional movements. In addition, while stabilizer muscles can play a role in machine-based training, these machines typically focus on primary movers rather than stabilizers. Muscles move the body by contracting against the skeleton, and strength-training machines are built to facilitate this process in a controlled and isolated manner.
