The FLX Ball is a perfect portable tool to add to a strength routine. This 9 inch ball adds a level of instability that challenges your muscles in a new way.
Working against the instability of the ball requires a full muscle activation. This, in turn, increases exercises effectiveness by activating key muscles necessary to complete the movement. Often when executing these simple exercises such as an abdominal curl, the body compensates to complete the movement by force, incorrect form, recruiting incorrect muscle groups, and gravity. Working with the FLX Ball allows one to perform the exercises in a correct manner with proper muscles activated, creating a quicker and more efficient workout.
