HOS - E118 This is a Hack Squat machine. It features a sturdy and durable metal frame structure, providing stable support for training. The equipment is equipped with weight plates that can be flexibly added or removed to meet different training intensity requirements. The unique inclined slideway design allows users to better isolate and exercise the quadriceps, gluteus maximus, and hamstrings while simulating the squat movement. Compared with free squats, it can effectively reduce the pressure on the lower back and lower the risk of injury. Whether for fitness beginners to gradually build leg strength or for professional athletes to strengthen lower - body muscles, it is a powerful choice for enhancing lower - body strength and shaping leg lines in both gym and home fitness settings.
