Dynamic Core is great for people trying to challenge their Core as well as their whole body. Either a Beginner or Advanced person, as long as you focus on the exercise and place emphasis on Body Mechanics, you will challenge your body.
Elbow Roll Outs on the Physio Ball place a huge demand on the Lower Back (Lumbar), therefore dropping to your knees throughout the Elbow Roll Out will ensure that the Core is worked without compensation. As soon as you feel confident in your movement and able to perform 15 + Repetitions, you will be ready to advance to the Physio Ball Elbow Roll Outs on your Toes.
Little steps at a time to ensure Quality Progress.
