1. Choose the right fitness video: Choose the fitness video that you like and suit your own level, so that it will be more natural and effective when you co-shoot with the video.

2. Adjust the playing speed of fitness videos: Some fitness videos can be played at the same speed as their own exercise rhythm. This way, when you are in tune with the video, you don't have to worry about the out-of-sync rhythm.

3. Warm-up exercise: Before you co-shoot with the fitness video, you should do a good job of warm-up exercise and let your body gradually enter the state of exercise, so that when you co-shoot with the video, you will not feel uncomfortable because of sudden exercise.

4. Keep breathing smoothly: Keep breathing smoothly when co-producing with the fitness video, and don't hold your breath or exert too much force, which will affect the exercise effect and health.

5. Don't over-imitate: Although you can learn the movements and skills in the video by co-shooting with the fitness video, don't over-imitate, and choose the movements and skills that suit you according to your physical condition and ability.

6. Cooperate with the music rhythm: If the fitness video has music, it can be in tune with the music rhythm, which can make the exercise more interesting and rhythmic.

7. Try more and practice more: You need to try more and practice more in co-production with fitness videos. Don't rush for success. You should adjust your movements and rhythms patiently and gradually find a way that suits you.

I hope the above methods can help you better cooperate with fitness videos. At the same time, we should also pay attention to safety to avoid injury.
