Rolling on the floor. It seems like a simple task. But many people seem to have a tough time with it. The simplest reason why is because they dive straight into it without the right body feel.
When somebody is initially taught the roll, they start off in a kneeling position, and the first point of contact tends to be their shoulder. Following the contact with the shoulder the next point of contact tends to be the lower back or rump. This is usually exemplified by a large thump or possible yell.
So why does this occur? The two culprits are body kinesthetic and flexibility. When a person is rolling they need to be able to feel the connection of their back to the floor. On top of that, they need to be flexible enough to round out their back to create the shape necessary to roll.
Where does a person start to gain the tools necessary. They should begin at the point of contact that most of the issues occur. That point would be the mid-back. Build the right body feel and flexibility in that area and the roll will be an easy task.
A great example on building this body feel comes from Ryan Hurst of GMB Fitness. Below, he demonstrates a set of progressions that you can use to develop the right feel to easily develop your rolling skills.
