a. most exercise machines are expensive to purchase individually.
b. most exercise machines require spotters for safe operation.
c. most exercise machines require less skill to use than free weights.
d. most exercise machines can only be used for a limited number of exercises.

please select the best answer from the choices provided.

○ a
○ b
○ c
○ d

Explanation:

• Option A: Exercise machines (like high - end treadmills, weight machines) are often costly when bought individually, so this is true.
• Option B: Most exercise machines (e.g., cable machines, some weight machines) are designed with safety features and do not require spotters. Free weights are more likely to need spotters. So this statement is NOT true.
• Option C: Exercise machines have fixed paths of motion and often have instructions, so they generally require less skill than free weights (which need more balance and form control), so this is true.
• Option D: Most exercise machines are designed for specific exercises (e.g., a leg press machine for leg presses), so they can only be used for a limited number of exercises, so this is true.

Answer:

B. Most exercise machines require spotters for safe operation.
