Yes, but don't watch violent movies and listen to violent music. One-time pile standing time is uncertain, so rest when you are tired. The longest time for a pile erection is 1 hour. The number of piles standing every day is uncertain. Don't entertain foolish ideas when standing a pile, you can meditate slowly on "relaxation" and "quietness" to eliminate distractions. Listening to light music is a good way to eliminate distractions. This method can be used for standing healthy piles and circular piles. I often use this method. Standing on a round pile is to change the overall force between the arm and the body shape into the force exerted by the body instead of the arm. It's actually very simple, but it's a bit difficult to practice. As long as the standing time is up, you will naturally succeed (but you must practice your strength and footwork).
