Women can use fitness equipment. Because there are differences between men and women, and the difference between male and female hormones is dozens of times, it is difficult for women to develop strong muscles even if they do strength training like men.

In bodybuilding theory, RM is used to indicate the maximum number of repetitions that a load can do continuously. For example, an exerciser can only lift a heavy object five times in a row, so the heavy object is 5RM. After 30RM load training, the number of muscle capillaries increased, and the endurance was improved, but the strength and speed were not improved obviously. Load weight of 5- 10RM is suitable for bodybuilding training to increase muscle mass. The weight of girls can be 20 to 30RM, and 20 to 30RM is mainly to improve endurance and has no obvious effect on muscle gain. Women often do light strength training, which helps to reduce excess fat and improve body lines. Proper muscles will make women's body lines more perfect, their bodies more beautiful and their skin more elastic.
