I'm scared to hang upside down. Is that normal? Will I even be able to push past it?

The fear of letting go with your hands or of flipping over is normal - almost every beginner feels it, and it's not weakness, it's just how the subconscious works. The main thing in our method: there's nowhere to fall, the straps hold your full weight, and the trainer is right there supporting you with their hands. We never flip you over by force and we never rush - we start small, little by little, and the body itself realizes it's safe and finally lets the tension go. People who clung to the straps at first are literally flying within a few sessions.
