Just about any exercise that can be performed on a piece of equipment at the gym can be replicated at home using resistance tubes. Exercises that do not require any equipment can be enhanced by using the resistance tubes to add a bit of challenge. Every major muscle group can be worked with resistance tubes, and by using lighter bands to perform simple exercises at a fast pace resistance tubes can even be used for cardio fitness.
For someone wanting to start a fitness program, or someone who simply wants to try something different in their workout, it would be hard to find a better option than resistance tubes. They can be taken just about anywhere, can be used for just about any exercise, and cost far less than any traditional piece of fitness equipment such as weights or treadmills.
