If you told your fitness instructor that you were interested in ski-specific exercise, she might advise you to "train the chain." The chain refers to the kinetic chain, which describes a biomechanical movement sequence. Optimal sport performance requires proper movement initiation and completion. Nordic and alpine skiing movements initiate in the feet, and follow through into the knees, thighs, hips and gluteal muscles. Ski machines simulate these kinetic chain sequences.
Types
Ski machines either simulate the arm and leg movements of cross-country skiing or the lateral movements of alpine skiing. The Nordic Track, which is a cross-country ski machine, provides independent arm and leg action. Downhill ski machines, such as the Skier's Edge, Pro-Fitter and Pro-Ski Simulator, use a single platform, which encourages simultaneous leg movements. Some downhill ski machines have arm poles. The Quadmill uses an undulating movement that simulates the extension and flexion movements of mogul skiing.
Features
Ski machines are either manually controlled or motorized. The motorized machines enable you to increase your pace. Some come with heart rate monitors, while others have optional accessories. The Skier's Edge, for example, has an upper body device. Attach it to the foot pedals for core exercise and upper body flexibility training.
Benefits
Most ski machines provide low-impact, weight-bearing aerobic exercise, sport-specific training and muscle toning. They also enhance balance and coordination. Since your feet stay in contact with the foot pedals, ski machines provide closed chain exercise. This type of exercise works multiple muscle groups simultaneously, thereby protecting the joints and helping to increase bone density.
Considerations
Ski machines cost between a few hundred and a few thousand dollars. The high-tech machines, such as the Skier's Edge and the Quadmill, are the most expensive. The Quadmill, weighing 435 pounds, is also enormous, and may not be suitable for home exercise. Consider your goals when choosing a machine. The Nordic Track may provide the most efficient aerobic workout, whereas the Pro Fitter and the Skier's Edge are best for simulating alpine skiing.
Warnings
The Skier's Edge and Pro-Fitter require skill and balance. Ask a friend or a trainer to spot you on the machine until you become accustomed balancing. Begin with slow movements. Consult your physician if you are new to this type of exercise.

The option not mentioned which has virtually all the benefits of the S. Edge machine and far more than the P. Fitter (in my opinion) is the Pro Ski Simulator, sold through skiformdotcom (www.Skiform.com). Not nearly as expensive as the SE, but more durable, quiet and stable than either the SE or PF. I bought one for skiing fitness and absolutely love the muscle and joint strength I get from using it.
