Leg extension A300Pro BL power is the best demonstration of the superiority of Keiser’s dynamic variable resistance over classic iron devices. The quadriceps are one of the strongest muscle groups in the body, producing very high forces at very high speeds. The knee is very sensitive to injuries at high levels of flexion, so at the beginning of the ROM (range of motion) we lower the resistance, increase it in the middle and add it to the maximum during the entire extension. This, along with your ability to work with each leg independently, maximizes your workout results while protecting your joints and connective tissue. On all Keizer machines, do heavy negatives – eccentric muscle contraction.
