When doing exercises, the weights used are different, and the aspects of key exercises will be different. The training mode of "big weight and few times" tends to increase muscle strength and volume, while the training mode of "small weight and many times" tends to enhance endurance and reduce body fat.
RM refers to the maximum number of repetitions, 1-4RM is mainly to increase strength, and 6- 12RM is the most suitable weight for exercising muscles and for muscle growth.

Principles to be followed in strength training:
1, do systematic training 2-3 times a week. The interval between two exercises should be at least 48 hours, giving muscles some time to repair.
2. First train the big muscle groups (such as chest, back and legs), and then train the small muscle groups (such as shoulders, forearms and abdominal muscles).
3, the elderly and hypertensive patients should measure blood pressure before fitness, because strength training will increase blood pressure. These two types of people should also pay attention to the burden of choice.
