pliability

It is a powerful way to get the day started. Staying in a difficult position activates the fascia and helps with mental resilience.

As the prior reviewer wrote you can tend to overextend yourself and have no guidance at all. It requires self-awareness of how far you can go.
My main objection is that despite doing it fairly consistently I do not feel more flexible at all. It lacks a focused approach to clear up existing misalignments. Sure, you have the Body scan which shows you exercises for target practices. But I haven't felt any major improvements after continuous training.

Improving flexibility, strong morning routine and forging mental resiliency.

Nothing

It is my very personal experience, but I have been seriously injured by Pliabilty. The concept is based on staying in one position for several minutes. I found it extremely difficult for beginners to get started. After a few days, I was asked to spend several minutes in the cobra position. 2 hours later I had severe back pain. The next day I could no longer move. I could hardly move for 2 weeks and after more than a year I still have problems. This training triggered something in me that was not good for me. That's why I personally can't give it a star.
