Hey guys...have you ever wonder why some muscles in your body grow faster that the others....or why there are guys with big chests and backs but small guns....or the oposite!....the guys with huge arms and poor chest/back development.......or the guy with huge legs and the only thing he does is squats......well a lot of this is due to genetics but the real reason may be the exersises we choose to do in the gym!!!
Some people are limb dominant and others are torso dominant....for instance what is optimal for some individuals might not be the best for you. If you are able to recognize how you were built you will clearly undertand what to do to to improve the inbalances in your physique.
This is part of an article writen by my favorite coach...Christian Thibadeau.....i was really facinated when i read it the man knows his stuff
I hope that you enjoy the reading as much as i did
He said: Proper exercise selection depends on your body structure (limb lengths, shoulder and hips width) as well as your muscle dominance. For example, the bench press or incline DB press are great movements to build the chest in individuals who are either "chest-dominant" (chest proportionally stronger than shoulders and triceps) or who have a balanced development in all the pressing muscles. However, if someone is "shoulder-dominant," these might not be the best choices.
See, it's not as simple as saying that compound movements are superior to isolation exercises. In many cases it's true, however in other case the proper isolation drill might be superior to compound movements.
Exercise selection is even more vital during a bout of low-volume training, because you must use a low number of exercises, 2-3 per muscle group. There's simply no room for a subpar movement.
While complete exercise selection depending on your body type and muscle dominance is outside the scope of this article and will be a series of its own, I like to use the following 'basic' guidelines when it comes to low-volume exercise selection:
• For a dominant muscle (a muscle that responds well to training) I suggest using only 'big movements': the exercises in which you can use the most weight for the target muscle group.
• For an 'average muscle' (a muscle that's neither a super easy responder nor a stubborn one) I recommend two 'big movements' followed by an isolation exercise.
• For a 'stubborn muscle' I suggest using a pre-fatigue approach: starting with an isolation exercise and then performing either one 'big movement' plus one more isolation one, or two 'big movements'. The key is to start with the isolation one.
Pre-fatigue is a technique that I recommend only for a stubborn muscle group. This technique is effective because by isolating a muscle you 'prime it' (both neurologically and physiologically) so that it's recruited more easily during the subsequent 'big movement'. The localized pump from the isolation movement also enables you to better 'feel' that muscle working during the compound drill (enhanced feedback) and are thus able to have a better mind-muscle connection with that stubborn muscle.
Here are some examples of possible exercise selections. Note that this is not an exhaustive list. You have my permission to choose other exercises.
