Isolationism can be a good thing.

Thomas Paine has a claim to the title, “The Father of the American Revolution”, because of his book ‘Common Sense’.

‘Common Sense‘, presented the American colonists with an argument for freedom from British rule at a time when the question of independence was still undecided.

Thomas Paine was what many called an isolationist, others a non-interventionist.  Thomas first published the book anonymously, full well knowing his views would bring some heat even though they proved to make sense.

It has been observed with muscle hypertrophy, that is tissue enlargement, that increases are delayed in muscle groups participating in complex multi-joint exercises like bench press and squats in comparison to single joint exercises like a bicep curl.

It certainly makes common sense as it is much easier to develop a single muscle fiber in the lab than a single muscle.  It is also easier to develop the musculature associated with a single joint rather than multiple muscles around multiple joints when doing one functional multi-joint exercise.

Exercise physiologists speculate this may be do to the neuromuscular challenge  posed by training a complex movement.

For rapid growth, isolation of tissue is a good thing.  Isolation exercises should be embraced not left out of a well organized program.

Develop the muscle tissue that you need as rapidly as possible and then go out and enjoy your sport.  Your brain will hook up the various hypertophied muscule structures and make it operate in a functional way.  It is only common sense.
