I am a male, 23 years old, and my height is 170. Because I didn't do much exercise for a long time, I grew to 150+, and then I had the idea of losing weight. At first, I went to the basketball court to warm up every morning, and then I ran for almost a month. I thought the effect was too slow and boring, so I wanted to find another way. I searched the Internet and found out about HIIT. I kept doing it for a few days, and then I saw other people's comments, saying that I had done insanity, which meant it was a piece of cake. So I went to the "Insanity" Post Bar, watched the essence question and answer of "Insanity" on Zhihu, and saw everyone's achievements, so I downloaded the video and prepared for the challenge. It was probably started around June 1 this year. I don't remember the exact date. On the first day, the fit test was half tired, and after it was finished, I had no strength. Fortunately, I ran for a while before, and the ten-minute video was followed up for a week or so, and it was still possible. The next day, my body was just sour and not painful. Because everyone in the Post Bar and Zhihu is emphasizing the importance of the standard of intensity movements, and coach Xiong T is also emphasizing it in the video, so I try to keep the standard of movements and do it slowly if I can't keep up with the rhythm. In the first week, the completion rate of each video was only about 60%, but after the first week, I didn't feel weak after watching it. On the contrary, I began to feel more comfortable. Sweating feels very cool. After the first month, the completion rate of each video is probably good. But unfortunately, I caught a cold in the fifth week, and it was still very serious. After the cold eased, my throat was still uncomfortable and I coughed. It took more than a week to fully recover. The following week, I jumped 2, 3 and 7 to regain my physical strength and prepare for the next month. Because the second month was too cruel, the intensity was directly improved to a higher level. Today I'm going to jump on the last day of the third week of the second month. Now only about 70 videos can be completed in the second month. I changed it a few days ago and jumped for a day. I really feel so relaxed that I can finish more than 90 without pressure. Now my weight is 140, and I have lost 12 Jin, and I feel very good. Of course, my goal has not been achieved, and I will lose about eight pounds. After the last week's dance, I'm going to dance the dance interspersed with Crazy and p90x. Whether you are trying to lose weight or keep fit, insanity is a good choice.
