TRX is a form of suspension training that uses body weight exercises to develop strength, balance, flexibility and core stability simultaneously. It requires the use of the TRX Suspension Trainer, a performance training tool that leverages gravity and the user’s body weight to complete the exercises.
TRX's designers claim that it draws on research from the military, pro sports, and academic institutions along with experience gathered from the TRX team, who work "with thousands of athletes, coaches, trainers, first responders, subject matter experts, professors, and service members in all branches."
TRX Training can improve mobility and stability, increase metabolic results, build lean muscle, and develop functional strength. Hedrick states that, "People who like yoga and Pilates tend to like TRX because there are some crossovers. But it's also great for golfers, runners, cyclists, or anyone who is an endurance athlete and wants to have more strength training.
