MAXIMIZE QUAD RESULTS

A300 LEG EXTENSION PRO

Model 1133

This Leg Extension Pro is the best to demonstrate the superiority of Keiser Dynamic Variable Resistance over Iron. The quadriceps is one of the most powerful muscle groups in the body, producing very high forces at very fast speeds. The knee is vulnerable to injury at high degrees of flexion, which is why we lower the resistance at the beginning of the ROM and bring it on heavy in the middle before backing it off at full extension. This, along with your ability to work each leg independently at speed, maximizes your training results while protecting your joints and connective tissue. And remember, you can do heavy negatives on all Keiser Dynamic Variable Resistance machines.
