that mirror
 

Sometimes when we look in the mirror we notice that one of our muscle groups are lagging behind the others. This can sometimes call for a change in our training routine.The first method is the Priority Principle. This should be obvious enough - if you want to improve one area more than others, make it a priority. Incorporating this principle is simple.First, train your lagging body part at the beginning of your workout. This way, you can dedicate all of your focus and strength to the body part in question before you've trained any other parts. This will eliminate the possibility of giving a sub-par effort due to exhaustion from other exercises.The priority principle doesn't end there, though. Improvement will come from working the lagging muscle group early AND often. There are a number of ways to add the "often" element. One way is to essentially make every set a superset, returning to the lagging muscle group after one set of whatever other exercise you perform.Another way is to intersperse a set or two for the lagging part in between each of your other exercises. This way, you will be drilling the lagging muscle more than your other muscles, but still allowing time for rest.By now, you can see that the key to promoting growth in an undeveloped area is to get that muscle moving as much as possible. Another way to do this is to employ more compound exercises in your routine.For example, let's say your shoulders are underdeveloped.*But because you're training other muscles as well, you were planning on doing triceps kickbacks for your triceps. However, that is a pretty isolated movement. In order to get your underdeveloped shoulders involved, try doing a military press, incline dumbbell press or dips instead. This way, you can get the benefit for your main muscle group as well as the lagging muscle group.Now if your training split involves you training only one body part a week, then you may consider training your lagging body part twice a week. Besides super-setting, you could flame them with drop sets or deep fry them a GVT hit and belt out 10 sets of 10 and other techniques like Time Under Tension (TUT).*The whole idea is to get that body part moving. Continous resistance and muscle fibre damage is what it needs. This will get it up to speed and never forget that your whole training split should be trained equally.
