Professional competence of work, there is a type of question I get asked all the time, which shows that many people are missing the big picture of the benefits of strength training. This popular question usually goes like this:
"What I can exercise my isolate _______ (insert choice of muscles - abdominals, quadriceps, biceps, triceps, etc.)?"
It does not matter which muscle someone to ask, they always seem to ask how to "isolate" him. The first answer to this question is always - why would you want to isolate?
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, most of the body to help other parts of the body already complex business. In fact, there really is nothing as true muscle isolation. It 's almost always close to the muscle group that helps in any way any movement you make. This article compares attempting to 'isolate' body parts via single-joint exercises much more effective strategy to make complex multi-joint movements.
When you try to 'isolate' muscles by performing single joint exercises, you are actually creating a body that is non-functional and will be more vulnerable to injury. Down, you must create an organization that is a collection of body parts, instead of a strong functional unit that works together.
Now, if you really want to end up hobbling around with a bandaged body, joint problems, tendonitis, and excess fat, then by all means, continue trying to 'isolate' body parts. On the other hand, if you prefer to be a lean, muscular, injury-free, functional unit, which acts as a complete unit to perform powerful complex movements (athletics or even everyday tasks), you must move the attention away from ' isolation of the muscle. Believe me, focusing on how your body will give you a side effect of a body that looks even better than you would if you focused on muscle isolation. For example, see the physicists of any NFL running backs, wing, or even a world-class sprinters.
Believe me when I say that these guys almost never train for muscle isolation (their strength coaches would not be crazy enough to let them), but they are completely torn to pieces! Just look at guys like Maurice Green or Terrell Owens and tell me who would not have a physical as these guys.
Another advantage of moving away from the mentality of "the isolation of muscles" mentality to a "movement complex" more is that you will find it much easier to lose body fat. The reason is that by focusing more on multi-joint complex movements in contrast to the isolated single-joint muscle, you not only burn calories more during each workout, but you also increase your metabolism and stimulate the production of fat burning hormones and more than building muscle, such as growth hormone and testosterone.
Here's an example. The leg extension machine is one of the joint exercise that works mainly the quadriceps, the knee joint may cause instability in the long term, and does not even burn a lot of calories.
On the other hand, exercises like squats, lunges, step ups, and deadlifts are all complex multi-joint movements that work hundreds of muscles in the body (including the quadriceps) as a functional unit, create more stable joints and stronger in the long run (when done correctly), and also burn lots of calories compared to single joint exercises.
