Why Exercise on an Unstable Surface?

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

“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.”**

Customer Reviews

“LOVE it! It’s the first time I have enjoyed doing abs in my workout. So much better than a ball, or working just off of the floor. Gives back support and still works out my abs thoroughly. Great for inner thigh squeezes and the lat pulldown position gives you stability while maintaining a great stretch.”


“I was pleasantly surprised with how simple and easy to use this product is. I definitely feel like I’m getting a solid workout with very little stress. It does feel very stable, too. A smart buy if you’re looking to get in shape or maintain good fitness.”


“I definitely got the best ab workout than I have from any other inflatable device. Love that it doesn’t roll out from under you. It feels easier to get and keep my balance on this core fitness trainer, unlike the large round balls. I spent more time trying not to fall off the ball than actually working out. Now I can spend a lot less time getting a safe, killer workout!”
