Training movements and muscles.
The Navy SEALs, who were looking to maintain their strength while on the move, created what is called TRX out of necessity. This highly portable performance-training tool leverages gravity and the user's body weight to complete hundreds of exercises. TRX Suspension Training develops strength, balance, flexibility and core stability simultaneously. TRX prides itself on “Training movements, not muscles,” and can be used for pre-habilitation, rehabilitation, and sport specific training purposes.
