The new epidemic has already changed people's living habits. Among them, home fitness has set off a wave, and some consumers have purchased related equipment for this purpose. Even if the epidemic is over, they may not return to the gym again. Under this trend, how can companies such as Lululemon and Nike use technology and big data to create a better "home fitness" experience? The epidemic has sparked a wave of home fitness, driving the sales of all kinds of home fitness equipment soaring, such as kettlebells, dumbbells, etc. all sold out of stock. Many start-ups and sports brands have also sensed business opportunities, launched various home fitness equipment, and used high-tech, big data and other technologies to create user-friendly "home gyms".
