Question

which of the following is not true of exercise machines? 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.

Explanation:

• Option A: Exercise machines (like treadmills, weight machines) are often costly when bought individually, so this is true.
• Option B: Most exercise machines are designed to be safe to use without a spotter (unlike free weights which often need spotters for heavy lifts). So this statement is NOT true.
• Option C: Exercise machines have guided movements, so they generally require less skill than free weights (which need balance and more form control), so this is true.
• Option D: Most exercise machines are specialized for specific exercises (e.g., a leg press machine for leg presses), so they have a limited number of exercises they can be used for, this is true.

Answer:

B. Most exercise machines require spotters for safe operation.
