Home > Quantum Fitness > Quantum I-Series Power Quad
- 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
- Patented* technology exclusively available by Quantum Fitness, a world leader in physical medicine and strength training products since 1990.
