I am getting older and I realized that I need to take care of my health. I minimize my food intake and I am concern of what I eat. I even avoid drinking alcohol and junk foods since last December 2008. Now, I need to work out and do some basic exercise. However, I am also busy and I have no time to go to the gym. Luckily, I discovered the way to exercise just at home. With the help of elliptical exercise machine, I don’t need to go to the gym. A recent study shows that varying the stride length on the elliptical exercise machine can recruit a larger muscle groups. The study also showed that as the stride is lengthened, more calories are burned without any higher rate perceived exertion by the user.
