TRX suspension trainers
In 1997 the founder of TRX used a jujitsu belt and some dust to make the first suspension trainer. This grew into Total Resistance eXercise (TRX). The company is now the best-known brand for suspension trainers. The trainers of the brand are sturdy and can be used in several ways: with a bracket on the ceiling or a special door clamp. With the TRX suspension trainers you train and stretch through the use of your own body weight. You also train multiple muscle groups at the same time, allowing you to train efficiently.
