The TRX is a versatile fitness tool, with a huge variety of multilevel (three dimensional) training exercises ( functional training) that are performed exclusively using only the body weight.
Most exercises require using many muscles at the same time, thus, the effects of training are maximized and become evident in a short period of time in comparison with conventional weight training.
Using TRX allows trainees to alternate exercises in seconds, minimizing the exercise time. Just 30 minutes of exercise in an hour, is enough to train all muscles.
