It's no use burying your head in blind practice if you don't know how to do it. Or you should go to the gym and ask the fitness instructor to teach you how to do professional muscle exercise.

Remember to have professional guidance, consult more, and practice blindly to get twice the result with half the effort. Not sure if it's semi-effective. . . .
