The original Octane elliptical just keeps getting better with the Q35 cross trainer, which delivers the form, function, and results that fitness users want. The Q35 is built around Octane's signature Body-Mapping Ergonomics motion, an extremely comfortable and fluid drive system that flows naturally--both forward and backward--without stressing your joints. As a result, even people with knee and ankle trouble can exercise hard. Octane also added several workout boosters. Called GluteKicker, ArmBlaster, and X-Mode, the boosters challenge and motivate you to even greater levels of effort. The GluteKicker booster targets your glutes, hips, and thighs, with intense lower-body intervals to get your legs in tiptop shape. The ArmBlaster booster does the same for your upper body, rigorously toning your pecs, biceps, triceps, back, and more. And for full cross-training, try the X-Mode virtual personal trainer, which includes eight challenging prompts to get your entire body working.
