The difference between action and exercise method, the meridians of exercise are still the same. Shi Deyang's version personally feels like broadcast gymnastics, without saying the main points or breathing coordination. Although you can't do miracles after practicing for a long time, you have enough fitness. If you are a beginner in practicing Yijinjing and there is no teacher to teach you, I personally suggest downloading the Chinese version of Yijinjing online. The videos and materials of this exercise are still relatively detailed, which can achieve the purpose of fitness. If there are other pursuits, we can refer to various versions of Yijinjing to study on the basis of Yijinjing.
