The two are better. Keep is a fitness brand headquartered in China, which provides online fitness courses, health management, smart devices and other products and services. Its core positioning is to help users carry out high-quality fitness training at home to meet the needs of users for fitness, fat reduction and shaping. Darrouy Yongji is a Japanese-based health care brand, which mainly provides products and services such as health care products and nutritional products. Its core goal is to provide consumers with high-quality health care products and bring people a healthier life through scientific formula and technology. Both have their own advantages and disadvantages, so it is difficult to compare which one is better.
