The Helix HLT2500 is the light commercial version of the world's first aerobic lateral trainer. The Helix delivers muscle sculpting results normally achieved only via weight training---all while conditioning the cardiovascular system and burning fat. Unlike conventional machines which work in a front-to-back plane, the Helix's horizontal "figure eight" motion allows users to target traditionally hard-to-tone areas while burning fat, delivering unprecedented results. Most aerobic trainers simply work the front of the thighs (quads) and the back of the legs (hamstrings), but the Helix also simultaneously works the inner and outer thighs and glutes. Users can alternate direction and weight bearing position to target specific muscle groups. Superb for sports-specific training, especially tennis, skiing and golf. At a compact 41" x 36" footprint, the Helix is smaller than a treadmill. The HLT2500 has a programmable LED electronic computer and smooth electronic resistance. The Helix HLT2500 requires no A/C Power. Manufacturer's Warranty 3 years Parts.
