Try TRX suspension training, which uses gravity and your body weight to make workouts more challenging. Heavy-duty adjustable straps, similar to the SEALs’ parachute webbing, are the basis of TRX. You can either buy straps (which cost about $200) and anchoring gear to use on your own, or take a TRX class at a gym or specialty studio.

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 is short for total body resistance exercise and uses suspension training for a complete, full body workout. According to the TRX website, suspension training is for everyone. It uses simple equipment and provides effective workouts. All you need is the TRX Suspension Trainer and your body weight.

TRX stands for total-body resistance exercise and Suspension Training refers to the type of bodyweight workouts you do with it. It was created by Navy SEAL Randy Hetrick as a way to keep him and his team in shape when they were deployed on missions where they had no equipment or space to work out.
