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. select the best answer from the choices provided.

It should be D

Consider a stationary bicycle. It does not exercise the arms the same way as it would the thighs. The chest muscles are not exercised in the same way as they would be by lifting weights.

It is true that they are expensive, but that truth is not relevant to the question.

I don't think you need a spotter. Other exercise procedures are far more in need of a spotter like a springboard and bars.

The free weights option requires some skill to get right so you won't hurt yourself. Most machines don't require that level of skill.
