I don't know if your pre-T or not. Certain exercises can increase your bulk, however overall strength and endurance should be your goal. To achieve this mix-up your routine, number of reps, amount of weight. Also don't push your self to the breaking point where your sore for the rest of the day/week. I am usually not sore or very slightly sore after a workout. This has possibly slowed my efforts to increase strength and endurance, but I haven't been set back by injuries.
I personally have muscles that are less tense at than the average person due to a health condition, which makes muscle size and tone harder for me to achieve. Your body maybe one that gains muscle tone, but not necessarily mass (as most people with E). It is my understanding that the longer someone has been on T the more the body gets use to the T driven system, which will lead to muscles being easier to bulk up.
