I have had this for a few years now. I must admit there were times I did not use it for a long stretch but when I did the results happened. I have gone from 275 to 155 pounds. I was diagnosed with Diabetes in 2012 and with the good diet and AeroPilates I have my blood sugar numbers under control and no longer need to take medication. I had both hips replaced last year I took the AeroPilates chart to my orthopedic surgeon he looked at the exercises and determined which ones to use a therapy thus avoiding Physical Therapist. I am now able to rebound again and look forward to getting the last 15 pounds the doctor wants gone off. My husband also uses our AeroPilates, he saw my results and started using it he is down 45 pounds. I love this machine so much I bought one for my Mom and one for my sister. If you want a comfortable effective way to exercise this is the machine for you.
