[TRNR strength band with 3 levels to choose from: light, medium, and heavy] The XL band is a training band that allows you to train in stages according to your individual level. By using moderate elasticity, you can strengthen muscle strength while gradually applying a light load. The two lines in the center with a different weave pattern are not only designed, but also effective as anti-slip. The refreshing mint blue that dispels the image of rugged muscle training goods is also attractive. It can also be used when you want to increase the range of motion of your joints with yoga and Pilates, or when you want to stabilize your joints. It is also a nice point that it uses highly durable materials and can be used for a long time. It is easy to clean because it can be washed even if you sweat.
