Quantum Fitness I Series Commercial Lower Body Gym


  • Lower Body Gym
  • The patented Quantum Power Quad is a revolutionary new way to isolate the quadriceps in a functional closed kinetic motion with more intensity than that of a leg extension
  • Sheer forces and patellar compression commonly seen with open chain activity are non-existent with the Power Quad
  • The Power Quad is not a leg press and is more effective than a leg extension for isolating the quadriceps
  • Unique pivot point and swing seat combination keep hip angle fixed through the entire range of motion
  • EMG readings verify greater activation of quadriceps on Power Quad compared to leg extension
  • Preventative and rehabilitation protocols for quadriceps strength, power and endurance can now be accomplished in a functional closed chain environment
  • Seat, backrest and foot support deliver safe joint angels to wide range of user sizes.
  • Frosted pastel shroud allowing for full user privacy
  • Weight stack: 250 lbs
