An elliptical cross trainer is comparable to a treadmill in its exertion of leg muscles and the heart. However, because the user's limbs remain in continuous contact with the machine, its operation limits the dynamic loading of bones and joints to generally harmless levels. This non-impact aspect appeals to those with recent injuries, chronic knee problems, and the obese, who cannot tolerate a treadmill. Ellipticals produce an intermediate range of leg motion between that of stationary bikes and treadmills.
- Treadmill is a Weight Bearing Exercise - Builds bone density and burns calories more efficiently. Inhibits the onset of osteoporosis.
- Elliptical Trainer is a Low Impact Exercise - Safe for joints. Ideal workout for people with back, knee, hips and joint problems.
There are claims that the dual action exercise of an elliptical trainers can actually be more efficient in burning calories. The logic is that by exercising more muscle groups simultaneously, a more intense workout can be achieved in less time. It is also suggested that the perceived rate of exertion is lower. However, other studies have shown that the rate in which calories are burned on an elliptical trainer is similar to that on a treadmill. Regardless, elliptical trainers are growing in popularity. One reason may be that because the person who is exercising is not taking his or her feet off of the pedals, an exercise can be done at a gentler rate, still getting the same amount of results as a treadmill.
For walkers and runners a treadmill is a logical choice. And the good news is the recent models are built for endurance and a pleasurable cardio experience. A Treadmill is the most efficient equipment to burn calories and lose weight, that is why they are the most popular.
You'll want a treadmill with a motor that is continuous duty with a rating of at least 2.0 HP. Continuous duty motors give you constant maximum power. Non continuous motors are unable to run smoothly for an extended period of time.
Select a treadmill that accommodates your stride with an adequate length and width. The deck should be at least 18" x 53". If you are a runner and tall, you may want to consider a "stretch" model. The deck should have a reasonable amount of cushion for minimal impact on your feet, ankles and knees. Several manufacturers offer extra thick cushioned treadmills as an option.
For variety you'll want a treadmill with incline control and computerized programming. Incline control simulates an uphill climb, while the electronics can be programmed to create a diversity of running or walking experiences.
