Sit down on the machine and adjust the bottom leg pad so that it's resting up against your lower shins. Keep your back straight and hands on the handles to your sides. This is your starting position.
Lift the weight up until your legs are almost straight and make sure not to lock them out. You should always keep tension in your legs for optimum movement efficiency. Then, lower the weight back down all the way until the machine still has tension in it. In other words, don't go all the way down as to allow the weight plates on the stack to bang into each other. Stop just short of this.
Finally, repeat the entire movement for the desired or prescribed number of repetitions.
