The Cybex™ Commercial 630A Total Body Arc Trainer’s broad incline and resistance ranges mean that users are really getting 3-4 machines in one. At the lower incline levels, the glide is a cross country skier. In the mid-range levels, the motion is a stride (like an elliptical except with proper positioning). At the high levels, the climb of a stepper or climber. One machine …the Cybex™ Commercial 630A Total Body Arc Trainer… trains for strength, power, endurance, cardio, and weight loss. Cybex™ Commercial’s Same Side Forward (SSF) technology makes it the only cross-trainer that allows a true upper body workout. SSF is an innovative motion that offers users the ability to vary the workout intensity between upper and lower body. All others use a cross crawl motion – the harder the upper body works, the harder the lower body is worked in response. This pushes up overall intensity which can put users out of their cardio zone before they get the training effect they are looking for. TheCybex™ Commercial 630A Total Body Arc Trainer combines elements of a climber, hiker, and skier to produce an unmatched number of workout combinations. By varying resistances and inclines, the same area can be targeted in different ways, to build muscle, burn calories … or both. For users stepping onto a cross trainer for the first time, or professional athletes who demand a high intensity workout, the unparalleled versatility of the 630A is a workout designed to achieve each user’s personalized fitness goals. Reverse Arc Motion is what makes an Arc an Arc. The unique Reverse Arc motion – a patented advanced stride technology – never places the user’s toe behind the knee (when the toe moves behind the knee significantly more stress is applied to the knee joint). The Reverse Arc motion moves legs in a biomechanically correct pathway – reducing stress at the knee while offering a complete range of motion for both the knee and hip.
