Combines a revolutionary new weight stack technology wit the most intuitive and user-friendly selection method ever created: a dial. Select weight with the simple turn of the aluminum dial. The dial is based on the incredibly successful Select Tech® dumbbells. The dial is always within reach from the seated position -- no more bending down, reaching behind or standing up to adjust weight selection. All units utilize a single weight tower design, always placed on the same side of the movement. The weight tower is only 47" high, creating an open, uncluttered look. Patented weight stack technology -- a rack of plates, stacked side-by-side. Turning the dial engages "hook" mechanism to select desired weight. Fewer pulleys and belts than current weight stack technologies, no guide rods and no weight stack pins. All machines (except Leg Press) come standard with 250 lb weight system that are adjustable in 1 lb increments. Total weight potential is 255 lbs. The Leg Press is standard with 425 lbs, adjustable in 5 lb increments. Total weight potential is 445 lbs. Range of motion limiters available. Supports and comfort from custom contoured, hand-crafted upholstery. Easy, smooth user set-up with standard hydraulic seat adjustments. Instructional placards are large and graphical - no text - and utilize lenticular images (they move as you move your head) to visually demonstrate correct movement. Proper machine set-up is facilitated by large red markers on axis points that aid users in proper joint alignment.
