HI, to be able to say what is the best workout, one would need to know what do you want from it. The workout from the link is very good for muscle size and strength. It was 2 times per week. You might need some cardio to enhance the process. (If you have endurance already, strength is a good next step.) After that you might want some speed and power types of workouts. (Maybe functional body weight - check MMA and functional training.) I think strength should take about 3 months and then the next step.. and then back to endurance -> strength -> power and so on
