Is going to have a pretty direct relation with how many cals you are taking in.
Of course how old you are and how long you have been traing are also a factor.
Well strength comes fairly easy to untrained or novice trainees, since the CNS adapts to stresses and is able to have wide room recruiting more fibers than a more highly trained lifter.
Size and strength has a correlation yes, so adding mass, especially as a more advanced lifter, can have good benefits, along with loads in the 75%-85% ranges for multi sets and reps, (ie: 4-6 sets of 4-10 reps) and using as much as 2-5 minutes rest between sets for close to 80%+ recovery for next set.
2 cents...
IMO, using that style of training or routine set up, will have you moving closer to goals of pure mass and strength, than a more cardio fitness muscle set up like circuit training or Xfit.
Hitting the big 5-7 compound exercises 2x per week. Using exercises that have you (standing on some especially) and loading the spine, like squats, deads, leg presses, rows, OHP's, BP's, will have more "systemic overload" and carryover to powerizing the entire large structures of the body than anything else I can think of and again IMO. (ie: old school stuff)
Along with using 80% of the body's mass, the heart and lung capacity gets a W/O too, as you adapt and slowly bump the capacity of the entire body to do more work.
