Explanation:

There are different machines in the gym or in the market, that are used to target specific areas of a human body. Doing machine workout helps in toning the muscles of the body. It is true that most machines are expensive to purchase by an individual. Also some machines are so complex that they require a spotter to operate it safely. And it is also true that some machines can only be used for a limited number of exercises. But it is not true by any means that most exercise machines require less skill to use than free weights. Free weights do not require any skill to be used. They can be used by anyone and for toning any body part by doing certain manual exercises with them. Using free weights is completely easy, rather most of the machines require skills to operate and use them.
