The boards can be very useful in teaching the layback and you will see how this 3 minute 2 second video lesson uses the boards to balance and set the free leg, hip and foot position for your layback. Janice does this in stages and you will see how simple each stage is. This really helps you arch and achieve the proper layback position which is critical and must have an arched back.
You will then see and hear corrections with demonstrators. You will then see a plain layback with all of the stages.
