A suspension trainer is a workout device consisting of straps and rings or handles.
It helps a person build up muscle and carry out body weight training. It's a useful tool for beginners to use their bodyweight to train.
The main resistance is the gravity that pulls you down and the weight of your body. You can change the difficulty of the workout by how long you extend the equipment and how far you lean lower to the floor. The higher you stand, the easier it is to exercise.
