The sit stretch

First, stand in front of the place you will sit and let the testicles and weight hang fully down one pant leg. Next, while standing, place one foot on the place to sit. Next, sit almost directly on the foot in such a way so that the heel of the foot is again the opposite hit joint. This will make the knee fully bent and the upper and lower legs will fold next to each other. As the sitting action is taking place, position the hanging testicles and weight so that the weight edge gets held in place by the low shin right above the ankle. As the sitting action is finished, the weight and testicles will be held back and held in place by the shin above the ankle and provides a strong stretch for as long as the user is seated.
