Everyone is busy making money, and you can't taste the benefits without experiencing this kind of thing in depth. You are not afraid of being tired and have no time. I started fitness because I was in poor health and felt threatened. I stayed up late the next morning, didn't sleep or eat, and ran directly 13 minutes. On the spot, it was dark in the park, as if it were getting dark .. I immediately walked slowly with my hands on the wall. Take a deep breath for a few minutes before going home for dinner, go to bed immediately, and then slowly resume fitness, because my health is too poor, which is the first time in my life that I feel so close to death.
