Stability trainer is used to improve motor skills and balance. Two foam pads of different densities and one air filled cushion allow users to work through progressive levels by starting on a firm surface and then standing on a pad. The green stability trainer is firm, and provides a beginning level of challenge. The blue stability trainer is soft and introduces an increased level of challenge to the user. For maximum challenge, use the extra soft black trainer. It is air filled to provide multiple direction displacement. One side offers rounded points to sensorimotor stimulation, and its heavy gauge side walls resist the tendency to roll the ankle during exercise.
