Step Walker®, A New Sensation for Leg Training, Launches on machi-ya by CAMPFIRE from February 21

Innovative Training with Step Walker®

Step Walker® introduces a new approach to leg training by integrating joint movements with Electrical Muscle Stimulation (EMS) technology. Unlike conventional EMS devices that primarily focus on muscle contraction through electrical stimuli, Step Walker® incorporates forward and backward leg motions. This combination allows the brain to recognize the joint movement, which is expected to enhance muscle response and lead to more effective exercise results.

This device is designed to address a lack of exercise and redefine the significance of walking. By combining daily EMS with appropriate training, Step Walker® aims to facilitate efficient routine workouts.

Verified Effectiveness

Electromyogram tests conducted by a domestic third-party organization demonstrated that Step Walker®’s full automatic mode (load levels 3-10) effectively engages muscles in the instep, shin, calf, and thigh. This suggests that users can strengthen their leg muscles simply by placing their feet on the device.

Flexible Training Modes and Joint Support

Step Walker® offers both automatic and manual modes, which can be used concurrently with the EMS mode for optimized training. The EMS directly stimulates muscles that are often challenging to train through walking or running alone, such as the sole of the foot, calves, and fast-twitch muscles, enabling highly efficient workouts.

Furthermore, the device targets the three essential joints required for walking: the hip, knee, and ankle. The automatic pedal rotation assists in improving the flexibility of these joints, which are often not consciously moved during daily activities.
