Combining elements of a climber, hiker, and skier, the Cybex 750A lower body Arc Trainer produces gym-quality results in any environment, helping you get fit more efficiently than ever before. The 750A is technically a commercial machine, meaning it excels in the most demanding environment. However, it’s also suitable for fitness-minded home users as well, with a compact footprint and a versatile, load-dependent design. The Arc Trainer is load dependent which means that resistance is scaled to the user’s weight. Two exercisers, one who weighs 250 lbs and the other 125 lbs, both get the same workout when they enter the same program levels and their own weight.
