This ultimately depends on personal preference, but from the software analysis, the overall ranking should be: keep, fit, hot fitness.

Personally, I have been using keep, and I feel very good. I also tried overheating fitness during this time, and I feel good. If you stick to fitness, you can stick to it yourself. Software is just a tool.

As far as my personal use and online access are concerned, keep is popular, accounting for almost half of the fitness apps, and then almost all second-tier competitions like splash, running laps, fit, hot fitness and so on. Compared with popular fitness, keep has more courses, more choices and group dynamics. Moreover, the functionality is strengthened and the development is faster. Hot fitness feels immature in many places. However, although its training movements are relatively few, it is basically enough. Hot fitness has more functions such as warming up before training and more detailed training suggestions than keep, which can be said to have their own advantages.

Now that the hot fitness has been deleted, I decided to use keep. After all, it's just a tool.

You can try it in detail and decide which one to use.
