Want to know our methods in the army? Considering that you are still young, I will arrange it for you like this. First of all, get up every morning, do sit-ups, 35 in each group, remember not to ask for help, do it yourself. The second leg, do you understand what the last leg means? It's the same as sit-ups, but on the contrary, the upper body is lying still, legs are straight up, and the height of the end is at an angle of 35 to 50 degrees with the body. Finally, 30 push-ups in each group. Get up in the morning and go to bed once or twice at night. Do this three or four times a day, and it will have obvious effects in one to two months. If time permits, you can ride more bicycles or climb mountains quickly. You should know what the accelerator pedal means. In other words, you can't only repair half the mountain, nor can you repair it at the most tired time, because the most effective time is the most tired time, including the exercise mentioned above. I hope our army's methods can help you realize your dream.
