A passive aerobic experience with a myriad of benefits, the chi machine gently cradles your ankles and swings to and fro while you relax, lying on your back. This creates a side to side movement that travels up from your feet to your head. The results of this gentle wave like motion are felt in as little as 10-15 minutes. Loosening tight back muscles, alleviating constipation and menstrual pain, and stimulating metabolism are just a few of the reported benefits.
