Why Exercise on an Unstable Surface?

From Applied Physiology, Nutrition, and Metabolism, 2010, 35(1): 109-112, https://doi.org/10.1139/H09-128

"The use of instability devices and exercises to train the core musculature is an essential feature of many training centres and programs. It was the intent of this position stand to provide recommendations regarding the role of instability in resistance training programs designed to train the core musculature.

The core is defined as the axial skeleton and all soft tissues with a proximal attachment originating on the axial skeleton, regardless of whether the soft tissue terminates on the axial or appendicular skeleton. Core stability can be achieved with a combination of muscle activation and intra-abdominal pressure. Abdominal bracing has been shown to be more effective than abdominal hollowing in optimizing spinal stability.

When similar exercises are performed, core and limb muscle activation are reported to be higher under unstable conditions than under stable conditions.

However, core muscle activation that is similar to or higher than that achieved in unstable conditions can also be achieved with ground-based free-weight exercises, such as Olympic lifts, squats, and deadlifts. Since the addition of unstable bases to resistance exercises can decrease force, power, velocity, and range of motion, they are not recommended as the primary training mode for athletic conditioning.

However, the high muscle activation with the use of lower loads associated with instability resistance training suggests they can play an important role within a periodized training schedule, in rehabilitation programs, and for nonathletic individuals who prefer not to use ground-based free weights to achieve musculoskeletal health benefits.”*

Benefit by Using the AbStar® 

In lay terms, the before-mentioned research study abstract means that the vast majority of exercisers can benefit from using a safe, unstable surface to enhance muscle use and recruitment. It means that you will use more muscles and you will use them differently at each moment due to the unstable base of the AbStar.

Although similar benefits can be achieved by using heavier weights or more active, sports-inspired actions, AbStar exercises are designed to minimize detrimental impacts on the body while maximizing positive effects. Thus, using lighter weights with the AbStar along with other total body exercises can give you similar benefits more quickly and safely than using heavier weights or high-impact-type exercises. That makes using the AbStar safe and effective for every exerciser.
