Titan is the best routine I've ever used, bar none. It doesn't need to be modified and shouldn't be. I'm tired of reading about how it's too tough and needs to be made easier. It will make you tough and then it will become easier, it should never be the other way around.
All you jokers trying to change the game just man the F up and work Titan the way it was intended. And it was intended to make you very strong and very big, very quickly. Consider it the Delta Force or Navy SEAL BUD/S of weight training, if you will. You can't handle it? then drop out but don't try to make it easier by cheating. Alright rant over.
