ASN505-A1 Hack Squat（Linear Shaft）

Product Features: The core difference of this device is the upgraded KBS optical axis slide rail system. Compared to traditional pulley systems, it operates more smoothly and quietly, offering greater stability during squats and push-ups, resulting in more natural movement transitions. This is especially noticeable during heavy weight training, where the track feels more responsive and stable, without any jerking or floating.

Another significant improvement is the overall stability during training. Many ordinary incline squat machines experience slight wobbling or less smooth movement as the weight increases, but this upgraded version, with its optical axis sliding rail structure, feels more solid and transmits power more directly. For those who frequently do leg strengthening exercises, this difference is very noticeable.

The shoulder pads and back support areas have also been thickened, providing a better fit to the body during training. There's no stiffness or shoulder pressure during heavy squats, leading to greater comfort during extended training sessions. The machine's robust steel structure provides near-professional-level stability, making it ideal for high-frequency training environments.

How to Use: Stand on the footplate during training, ensuring your shoulders and back are firmly against the support pads. Adjust the stance distance according to your training needs. After unlocking the safety device, slowly squat down, keeping your legs in control of the movement. Pause briefly at the lowest point, then use your quadriceps and glutes to push the weight back up. Maintain a steady rhythm throughout the exercise; avoid relying on momentum to bounce up. The more you control the movement, the more noticeable the leg muscles will engage.
