It is a load a crap and why continues to be used as a selling tactic is just a downright travesty.
But you and I both know we have certain parts of our body that we love... parts that we want to look "cool" or "sexy." The great thing is, with a program that concentrates (2 week muscle zone concentration)... but remains total body, you can achieve a pseudo spot reduction and build up a particular body zone.
Spot Reduction Doesn't Work
Spot reduction doesn't work because the body doesn't burn fat in just one area. I won't lie... how cool would it be if it did?
Your body is efficient at burning fat but it is almost like a hierarchy. It burns fat evenly throughout your body... so the spots that have the least fat see the fastest results. Most people will almost always notice their arms and legs getting muscular first before their midsection.
The unfortunate fact of this is... your abdominal fat is the last to go... usually because it has the most fat surrounding it.
That is why I always tell you to do your squats, deadlifts, and other compound moves. They burn the most calories and when that happens you speed up the fat burn across your entire body.
Why do compound exercises burn the most calories? - because they involve the most muscle. What do you think? If you work just your bicep... do you think that will burn more calories than working your legs and core at the same time?
Of course not... that is why compound exercises are far superior.
Concentration Can Help With Pseudo Spot Reduction
This is dangerous to do and you have to work with a really good trainer to make sure you don't develop dysfunctions. But you can concentrate on your favorite muscle group and build that up simply by adding a few extra exercises that isolate that muscle group.
However, after say a 2 week period of concentration, your body will be slightly out of balance so you have to make sure you work the opposing muscle group to bring things back... or else you could suffer pain and issues.
One of the biggest issues is that people don't build their bodies evenly. For example... most guys will work their upper bodies more than their lower bodies and women will do just the opposite.
They then wonder why their results have stopped. There body is simply out of balance and then need to bring things back to equilibrium to continue making great gains. So remember that you can't spot reduce any particular muscle group... but you can use concentration programs to build something up.
Balance and consistency is key to getting those results.
