Select the desired resistance on the weight stack and insert the pin. Adjust the seat so that the knees are directly in line with the axis of the machine. Sit down and position your shins behind the pad at the base of the machine. Take a deep breath and extend your legs as you flex your quadriceps. As you lock out the knees, exhale to complete the repetition. Slowly lower your feet back to the starting position and repeat for the desired number of repetitions.
Align the machine’s axis with your knee joint to avoid stress or injury. Avoid using excessive weight since quads work without hamstring support. Pointing the toes can improve mind-muscle connection.
