What you need to know about Weight Training for a strong lean body that both looks good and is injury resistant

Image via WikipediaWorking as a personal trainer & fitness professional, there is one type of question I get all the time that shows that many people are missing the big picture regarding the benefits of strength training. This popular question usually goes something like this:

“What exercise can I do to isolate my _______ (insert your muscle of choice – abs, quads, biceps, triceps, etc)?”

It doesn’t matter which muscle someone is asking about, they always seem to be asking how to ‘isolate’ it. My first response to this question is always – “Why in the world would you want to isolate it?” 

The first thing I try to teach my clients is that the body does not work well in muscle isolation. Rather, it works better in movements along a kinetic chain; that is, large portions of the body assist other portions of the body in completing a complex movement. In fact, there really is no such thing as true muscle isolation. There is almost always a nearby muscle group that will assist in some way with whatever movement you are doing. However, this article compares attempting to ‘isolate’ body parts via single-joint exercises to the much more effective strategy of performing multi-joint complex movements.

When you attempt to ‘isolate’ muscles by performing single-joint exercises, you are actually creating a body that is non-functional and will be more prone to injury. Essentially, you are creating a body that is a compilation of body parts, instead of a powerful, functional unit that works together.
