Dual-function design, comprehensive shaping Synchronised training of inner and outer thighs: Combining the functions of leg adduction and leg abduction, it can simultaneously exercise the inner thighs (adductors) and the outer thighs (abductors), shaping a well-proportioned leg line. Multi-mode switching: supports continuous contraction, intermittent contraction and cycle exercise modes to meet different training needs for muscle building, shaping or rehabilitation. Adjustable Resistance for Multi-Phase Training Adjustable resistance: Equipped with an adjustable resistance device, users can flexibly adjust the training intensity according to their own fitness level (e.g. novice, advanced), and gradually improve muscle strength. Progressive weights: Wide range of resistance supports the transition from low-intensity rehabilitation training to high-intensity muscle building training, avoiding the plateau period. Ergonomic design for comfort and safety 360 Adjustable Seat and Leg Pads: Seat height, angle and leg pad spacing can be adjusted to suit users of different sizes, ensuring a standard training posture and reducing stress on joints. Anti-slip footrest and handle: Anti-slip texture design of the footrest and stable handle improve training stability and reduce the risk of slipping or losing balance. Durable material, quiet and stable Thickened steel frame structure: The main body is made of high-strength steel, with strong load-bearing capacity and no deformation in long-term use. Silent track system: resistance adjustment and movement process is silent and smooth, avoiding interference with others, suitable for home or flat environment.
