The DYNADISCTM has become a staple in training protocols of all kinds. The DynaDisc is the simplest, smallest, most dynamic effective exercise device available today. It can be used for training: mobility and a range of motion (flexibility), muscular strength and endurance, and postural stabilization (balance).
The DynaDisc is made of the same material as a gymball. It is fourteen inches (14") in diameter, is beveled on the edges for comfort to the hamstrings, comes in four colors (green, blue, red and yellow), can be inflated with the use of a traditional ball needle and can withstand up to two thousand (2,000) pounds per square inch.
