The standard kneeling rollout is the first exercise to master before you try it standing, which is the ultimate test. It teaches you how to resist extension as the lever of your body gets longer as the hands go out overhead.

The main focus is to make sure that your hips don't tip anteriorly and the lower back isn't hyperextending, especially during the transition point when your hands are the furthest overhead. When you can comfortably complete 3 sets of 15-20 rollouts without any pain or "working" sensation of your lower back, you're good to go. – Kyle Arsenault
