The TRX is very easy to use. As long as you have a place to attach it to, you are set to have your own portable gym. Former Navy SEAL Randy Hetrick, the inventor of the TRX guides you through setting up the TRX Suspension Training System.
How to set up the TRX:
Find an overhead anchor point 7 to 9 feet above the ground that can support your body weight
The black loop should hang about 6 feet above ground.
Wrap the suspension anchor around the anchor point several times to help secure the straps and then fasten the carabiner into the appropriate loop.
Weight test the TRX before starting exercises.
