Some machines feature very easy adjustments to convert from one set of oblique exercises to another. Other machines have more complex features. Keep in mind that a multi-station unit will require some maintenance. You will periodically need to check the cables. You may also need to add lubricants. It’s important to follow the manufacturers specific care directions that accompany the equipment. Before you invest several thousand dollars, it’s a good idea to check out the manufacturer’s warranty for the product. Find out what type of customer service and support is offered. Some sporting goods store will include consultation and set up with your high-end equipment purchase. Ask if the store will help you if the machine breaks or whether you need to deal directly with the manufacturer. Go ahead and call the manufacturer’s toll free number to find out what type of maintenance support is offered. Doing these things ahead of time will save you trouble in the end.
