select the correct answer.
sam has been working to improve his muscular fitness. he jumps rope and trains with weights. what will most likely be the result of sams efforts?
a. increased motivation
b. decreased flexibility
c. increased bone density
d. decreased metabolism

Explanation:

Weight - bearing exercises (like jumping rope and weight training) stress bones. This stress stimulates osteoblasts (bone - building cells). As a result, bone density increases over time. Motivation (A) is more of a psychological aspect not directly tied to these physical activities in the context of the question. Flexibility (B) can be maintained or even improved with proper weight - training form and if combined with stretching (jumping rope can also have some aspects of dynamic stretching). Metabolism (D) is likely to increase with muscle - building activities as muscle tissue is more metabolically active than fat tissue.

Answer:

C. increased bone density
