Tokyu Sports Oasis Twist Stepper You can easily do aerobic exercise and lower body training at home, and you'll feel warm just by using it for 10 minutes. As you train for a long time, the large screws may loosen due to the vibration, causing a clicking sound, but tightening them will restore it. This seems to be a standard specification, as it was a common phenomenon in reviews at the time of purchase.
