Yoga is for everybody. But, not every yoga posture is for everybody—including Chaturanga Dandasana. For many practitioners, the pose is simply too demanding to be done with safe, stable alignment.
Chaturanga Dandasana is hugely common in vinyasa flow classes and often vilified or blamed for all sorts of injuries. Some of that may be true, especially if done quickly, forcefully, and without any concern for alignment. I prefer to think positively about what chaturanga delivers, although extolling its virtues may fall on deaf ears and tired arms. With sincerity, I believe it is an efficient and effective transition from plank into upward-facing dog, priming the strength of the arms and shoulders to deliver the backbend energetically as well as giving an opportunity for rhythmic breath and movement.
