About a year ago my weight was 235-240 and I felt bad all the time. My doctor told me I needed to start exercising. I bought the Revolution, but never had the discipline to use it. After my doctor visit I decided it was time to get started. So I began working out pretty much every day and a year later I now weigh 200 with 18" arms and a 50" chest. The best thing I like about the Revolution is that my joints never hurt. I used to work out when I was in the Marine Corps and my joints would hurt due to the free weights. Now I am over 48 years old and working out harder than I used to with absolutely no joint pain. I just wanted to say thank you for your machine that has kept me going and I am sure will keep me going for years to come. I actually enjoy working out every day now.
