The vast majority of fitness experts and athletes that we surveyed agree that elliptical machines such as the Life Fitness 95Xi and Precor AMT 100i are the best cardiovascular pieces of fitness equipment today at gyms and health clubs across the nation, due mostly in part to their ability to efficiently elevate user heart rate and burn calories and at the same time, they do not do harm to your knees and other body parts, like regular running on a treadmill can. These top-shelf, health club quality elliptical trainers will exercise your quadriceps, hamstrings, arms, stomach, back, buttocks and really help eliminate love handles. Separating elliptical machines from treadmills is the fact that an elliptical will do all of this, with a no impact workout, keeping your knees, hips and ankles happy.
Even the most expensive treadmills at the top of the class do not provide the very gentle running motion, that is easy on your joints, like an elliptical does. One of the best parts about working out on a cross-trainer, rather than a treadmill, is the fact that once you are done with your workout, you will not have to take an epsom salt bath or ice down your knees.
There is a ton of literature out there on why ellipticals/crosstrainers are better tools for cardiovascular exercise than treadmills. However, the only thing that should count is whether or not the stride on the elliptical fitness trainer is as comfortable, or more comfortable, than the treadmills you are used to running on. One should always remember that the true test of how well a piece of fitness equipment will work for you, is always solved by actually trying the different gym machines and then determining their value to your workout program.
