Zero gravity striders are non-powered cross trainers designed for home use. They use a swinging leg action that mimics walking. Although the original Zero G Strider is no longer in production, there are numerous similar products available that work the same way. Most zero gravity striders are quiet in use, collapsible for easy storage and very simple to operate.

Low Impact Exercise
The striding action offered by this type of exercise equipment is low impact. This means that there is no shock loading of your bones, joints or muscles during use. Low impact exercise is ideal if you suffer from joint problems such as arthritis or bone conditions such as osteoporosis. Exercisers who are overweight will also benefit from using a zero gravity strider because the impact that results from walking and running can cause injuries to your feet, knees and hips.
Striders have a combined leg and arm action that uses virtually every muscle in your body. By pulling and pushing the handles as you stride, your upper body gets an effective workout along with your legs. Using your arms and legs together increases the overall demand and calorie-burning effect of your workout. If you are a beginner, focus predominantly on your legs when using a strider. As you become more proficient, increase the amount of work you do with your arms.
Improved Aerobic Fitness
Using a zero gravity strider uses all of the major muscles in your body. As you work out, these muscles demand a large amount of oxygen. Oxygenated blood is pumped around your body by your heart. As a result, your heart and lungs will get fitter and healthier. According to the American College of Sports Medicine, there is a direct link between aerobic fitness and a reduction in cardiovascular disease. The ACSM states that people who are aerobically fit are less prone to coronary heart disease, heart attacks and strokes.
Increased Bone Density
Although using a zero gravity strider is a low impact exercise, your bones and joints must still support your body weight. Weight-bearing exercise increases the mass, density and strength of your bones. As a result of weight-bearing exercise, cells called osteoblasts are produced that promote skeletal health. Increased bone mass can reduce your chances of developing osteoporosis. Osteoporosis is associated with weak, porous bones prone to fracture. The most common sites for osteoporotic fracture are the hip, spine and wrist. All of these areas are strengthened by regular strider workouts.
