Question

b. they both use free weights.
c. neither exercise is isotonic.
d. they are both arm exercises.

please select the best answer from the choices provided.

○ a
○ b
○ c
○ d

Explanation:

• Option A: Barbell curls and dips target arms, not legs, so A is wrong.
• Option B: Dips typically use bodyweight or parallel bars, not free weights, so B is wrong.
• Option C: Both barbell curls and dips are isotonic (involve muscle shortening/lengthening with movement), so C is wrong.
• Option D: Barbell curls work biceps (arm), dips work triceps/chest (but primarily arm - related movement), so they are both arm - focused exercises.

Answer:

D. They are both arm exercises.
