The Hammer Strength Iso lateral Leg Extension-A unique way to work the quads.
This leg extension is unique because it allows independent motion of each leg. The user can work one leg at a time or both simultaneously without the dominant leg doing most of the work.
The first picture at the left shows the beginning postion of the exercise. My knee's are bent approximately 90 degrees and the shin pads rest just above my ankles. I also maintain an upright posture while seated. This will promote good posture. The second picture at the left shows full extension of the legs before returning to the start position. In this contracted position I focus on squeezing my quads to enhance the contraction further. I then control the downward motion and return to the start position.
In order to achieve proper postiioning in the machine (shown in the first picture) there are a couple of important adjustments you need to know about. The third photo shows a red dot on the macnine. The axis of rotation of the knee should line up with this dot. Basically, line up the knee joint where it bends with this dot.
In order to line up the knee joint properly you may have to adjust the seat forward or backward depending on your leg length. The last photo shows a simple seat adjustment to ensure good position. If the seat is too far forward your knee will be forward of the dot. If the seat is too far back the position will be uncomforable on the back of your leg and your knee will not line up with the dot. The manufacturer includes this simple landmark to make the machine more user friendly.
