For a triceps extension with toning tube an exercising ball is required, sit on the exercising ball with a straight torso, with your legs making a 90 degree angle with your knees; take a toning tube and grab on one of its handles. Now move your hand with the handle above your head, with an elbow bend dropping the tube on your back; with the other hand reaching back and grabbing the tube from underneath both your hands are on your back now. With the upper hand holding on to the tube, the triceps extension with toning tube is now in position; simply stretch the tube with the other hand and feel the pressure.
