TRX or suspension trainer was created by former U.S. Navy SEAL Randy Hetrick. This equipment uses your body weight to develop balance, strength, core stability, and flexibility all at the same time. It is a perfect tool for those people who want to train all at once. TRX will indeed help you to get in shape in no time but you should know that total resistance exercises are pretty challenging. So if you are ready for challenging workouts, go ahead and give it a try.
