workout routine help!!

[liftingfreak1983]

hey guys i've been doing DC's routine for some time now and have got pretty good gains but now that i don't have a spot any more it is pretty hard to lift at the intensity that i used to...anyways i was considering switching up my routine and i've read over the 5x5 and HST. any suggestions btw i am 20 years old at about 6'0" 200lbs im also pretty lean. what i want to do is put on real lean mass...thanks for all the help

another thing is that i really dont understand HST that well and about 5x5 i was curious if you do the three day rotation and what muscle groups do you lift on what days?
