• The gluteus maximus, the main muscle that forms the buttocks. Exercising this muscle not only tightens your buttocks and lengthens your legs, but also improves your metabolism, prevents back pain, and improves your posture.
• With WBN310, even beginners who don't know how to use muscles can exercise effectively using the gluteus maximus, so I recommend it.
• You can easily use it anywhere, such as while watching TV, during housework, or while brushing your teeth. It is characterized by being easily incorporated into daily life.
• Easy training just by putting it between your legs
• Muscle training without taking up too much time with exercise
• You can also use it to train your thighs, chest, back and thighs.
