- In physical training it is common to use some sort of additional load to increase the effort and effect of the workout. Typically, weights are used where the combination of repetitions and size of the weights are used by an athlete to attain he desired results. Traditional weights do not give any feedback to the user regarding amount of effort, number of repetitions, technique or other factors related to the workout.
- In some endurance sports like running, cross country skiing, swimming etc. it is important to increase the muscular strength for both high intensity activity and endurance for sustained periods of physical activities. To increase the effort of an activity the athletes usually exercise with some additional load like pulling car tires when running. A rope is attached to the tire and the athlete pulls the tire by the rope while running. Such pulling of tires by a rope does give any information of the quality of the exercise. Many athletes want to monitor their muscular strength development and being able to adjust the exercise plan according to progress and fitness level. This is not possible with existing equipment for pulling car tires or other weights when running.

The athlete then jumps or runs away from the wall to stretche the elastic band. The stretching of the elastic band requires effort by the athlete and is used to increase the effort needed to perform an exercise. Elastic bands do not provide any feedback of effort, profile of effort, number of repetitions or other information that the athlete could be used for improving the quality of the workout.
