Why people think they need flexibility:
Yoga is often shown as advanced poses and very flexible bodies, which can make it seem like flexibility is a requirement. In reality, yoga is for everyone, you don't need to be flexible to practice.
What a yoga class actually requires:
A willingness to move gently, listen to your body and choose the option that feels right for you. Not forcing yourself into a shape because you think you should be there, especially if it causes pain.
What progress can look like:
Progress is not just reaching a shape. It can mean feeling more comfortable, more confident and more aware of what your body needs.
