Check out cross fit!just search it on google and you should grasp the idea,of not drop me a message! but if you really want that muscular build everyone looks for then incorporate this into your bulking routine. take no more than 2 days a week on it and just do pure cross fit! you will burn fat so fast i promise you! still bulk as usual on the other 5 days of training and you wont loose any muscle! and if you do, check your diet! please drop a comment if you need more info!
