It's a complete thigh contraction extension exercise.

It places terrific tension on the leg muscles from start to finish of each repetition.

It improves over-all balance and control for the bodybuilder, and helps to make Squats more easily and more correctly performed.

It increases flexibility of the legs.

It speeds muscle growth and power development even for the advanced bodybuilder because each hip and leg is exercised separately, thus enabling a massive, concentrated effort to be focused on each.

You'll need your Weider Power Stands for this fine exercise and here's the way it's done:

Place your Power Stands in position and adjust their height so that this will correspond to the height of your shoulders when you are in a deep leg split as for a heavy Clean.

Place a suitably loaded barbell across them; grasp the bar (which will rest against the back of your neck); extend your feet forward and backward until you are in a deep leg split.

Now raise the weight by straightening your front leg, without moving your feet. When the front knee is straight and locked, allow it to bend again until you feel the bar come lightly into contact with the sides of the Power Stands.

After you have taken a breather, reverse the position of your legs so that the front thigh of the previous exercise is now to the rear, and the rear thigh now to the front, and perform the same movement in the same manner.
