Free-weight training refers to self-exercise with the help of simple weight-bearing equipment such as dumbbells, barbells and kettles. In recent years, emerging gym brands, such as DP Fitness, have relatively simple equipment, and most of the actions you are taught can be done at home, that is, self-weight training. Generally, large-scale equipment is suitable for practicing muscle mass, and self-weight training is suitable for practicing muscle lines, which is more suitable for Asian aesthetics.
