When we were in school, there was a big recess every morning, and all the students in the school had to do this gymnastics operation along with the music. I hated this at the time, but now as an independent developer who sits in front of the computer all day, I find it very useful - it only requires a small space, one or two square meters in front of my desk, no equipment, and exercise It's not very intense, but it can exercise most of the muscles in your body. Even if I only have 1-2 minutes to complete a small section, I feel that I remind myself to stand up from the chair and follow the exercises several times every day, and my mental state has improved a lot. I'm sharing this because maybe it will be helpful to someone else.
