The TRX suspension trainer was developed by Navy Seals and is intended to use gravity and body weight to challenge the muscular system. The reason I love TRX is that it is safe and there are simple ways to make an exercise easier or more difficult depending on your level of athleticism. For easier modifications, simply changing the angle of your body in comparison to the TRX will make it less difficult while adding a hop to lower body exercises can add intensity. The below exercises are rated for beginner's to intermediate.
Repeat circuit 3 times.
