Wheel roll out
Place knees on a comfortable surface and align the wheel underneath the shoulders. Squeeze the abs and glutes as tight as possible.
Roll the wheel slowly out in front while keeping tension in the abs. Keep the back as flat as possible. If the lower back begins to sag to the ground, the stress will be put on the lower back.
Roll the wheel back towards the knees. Do not let the hips shoot back first. Raise the torso with the hips as the wheel is rolled back.
