I purchased this new from the official shop and used it a few times. I am selling it because it didn't suit me. Operation has been confirmed. There are no noticeable stains or scratches, but please understand that this is a used item before purchasing. To prevent any problems, please refrain from returns or claims. There is also the instruction manual and a mat to place underneath (unused). Since I don't have the original box, I will pack it in a cardboard box with cushioning materials. Please note that I can only ship on weekends.

Features Equipped with two functions: twist mode & aero mode The Twist Aero Stepper created by a fitness club allows you to switch between muscle training (twist mode) and aerobic exercise (aero mode). It has a quiet design that reduces noise. This is a special stepper that allows you to exercise for about 60 minutes continuously. Aero Mode Aerobic exercise with light steps Shapes the hips and lower limbs Twist Mode Twist exercise with twists to the left and right Shapes the waist and lower limbs You can change the area you train by the direction you step on The Twist Aero Stepper allows you to change the area you train by the direction you step on. Stepping on it facing forward trains the front of the thighs and the buttocks, while stepping on it facing backward makes it easier to perform twist exercises and train the inner thighs. *For a while after you start using it (especially when the temperature is low), you may feel that the load is heavy. By stepping firmly with each foot alternately, the cylinders will gradually warm up over time and move smoothly. Thank you for looking.
