As an easy-to-carry, simple and very effective small physical training tool, the elastic band is known as the smallest fitness equipment in the world. It has been used in the field of fitness more than 100 years ago and is one of the best auxiliary tools for fitness.

Resistance bands are surprisingly small compared to traditional dumbbells or barbells, but you might find it hard to believe that resistance bands are a great strength training tool.

Elastic bands may not give you a more intuitive training effect and feeling like dumbbells and barbells, but their strength affects your training effect subtly.

A single seemingly “inconspicuous” band can help you strengthen all the major muscle groups in your body, and many people experience the power of resistance bands the day after their first workout.

Due to their versatility, resistance bands are also more efficient. Biceps curls with dumbbells are a fixed movement and the muscles used are predictable. And the instability caused by the resistance band itself causes the muscle fibers around the arms and shoulders to work to maintain the stability of the associated joints and muscles.
