C Correct answer
Explanation

Shrugs involve pure vertical scapular elevation with no shoulder joint movement - isolating trapezius. Bench press uses anterior deltoids, dumbbell rows use posterior deltoids, and military press heavily uses all three deltoid heads.

AI explanation

To answer this question, you need to understand the muscles involved in each exercise. Let's go through each option to understand why it is correct or incorrect:

Option A) Bench press - This exercise primarily targets the pectoral muscles (chest), but it also involves the anterior deltoid muscles (front of the shoulders). Therefore, this exercise does involve the deltoid muscles.

Option B) One-arm dumbbell rows - This exercise primarily targets the latissimus dorsi muscles (back), but it also involves the posterior deltoid muscles (back of the shoulders). Therefore, this exercise does involve the deltoid muscles.

Option C) Shrugs - This exercise primarily targets the trapezius muscles (upper back and neck), not the deltoid muscles. Therefore, this exercise does not involve the deltoid muscles.

Option D) Military Press - This exercise primarily targets the deltoid muscles (shoulders) as its main focus. Therefore, this exercise does involve the deltoid muscles.

The correct answer is option C. This exercise, shrugs, does not involve the deltoid muscles as its primary target.
