Suspension exercise has been a way for athletes to train when away from a gym, most notably TRX developer Randy Hetrick, former Navy Seal Commander. This type of body weight suspension training activates the core, and builds strength and mobility. The 133-page StretchTension Manual translates suspension exercises to the aquatic environment using NZ StretchCordz®. Developed by aquatic specialist Anne Pringle Burnell, the manual includes a table with progressions and regressions of the exercises. StretchTension benefits include: strength and agility without joint load, increased performance, and improved balance recovery.
