well then you don't need to worry about increasing your training loads then, but as you get leaner and lose fat you gotta be sure and maintain them training loads, coz if you don't then you will lose muscle PERIOD
the way to get lean and tighten up is to eat less cals (yes, it's as simple as that)
it's simple to know what to do, but to actually do it is a totally different matter, coz most peeps pussy out and eat too much as they can't handle the pain and discomfort of starving
