Which of the following is NOT a benefit of using bands and chains in bodybuilding?

Using bands and chains in bodybuilding is known to provide several benefits that enhance performance and results. Among these advantages, implementing equipment like bands and chains can lead to improved strength curves, enhanced muscle tension throughout the range of motion, and increased training variety, which helps to keep workouts engaging and effective.

The reason that less energy expenditure is not considered a benefit is that bands and chains can actually increase the energy demands during workouts. This is due to the unique resistance they provide, which typically varies throughout the range of motion. As the muscle lengthens, the tension may increase with bands or chains, requiring more energy to overcome this resistance compared to standard weights alone. Therefore, while bands and chains are effective in modifying resistance and promoting strength and variety in workouts, they do not contribute to reduced energy expenditure in the way that might be expected.
