THE DISADVANTAGE OF USING WEIGHT MACHINES IN THE GYM

Posted by stephan van breenen on May 4, 2013 at 8:20 AM

.CONSTANT RESISTANCE MACHINES IN THE GYM....

*CABLE/CHAIN ARRANGEMENT...WHERE YOU PULL A STACK OF WEIGHTS

WHAT TRAVELS THROUGH A PULLEY....WHEN YOU LOOK AT THE PULLEY

THE DISTANCE BETWEEN THE AXIS AND THE PULLEY...AND THE OUTER EDGE

OF THE PLANE(OR WHEEL OR PULLEY IT MOVES) OUTSIDE OF THE PULLEY

IS NOT AT THE SAME DISTANCE AS THE AXIS ALL THE WAY LINE OF THE PULLEY

HENCE THERE WILL BE A POSITION WHERE THE OUTSIDE EDGE OF THE PULLEY

IS AT A LESS DISTANCE...THEN ANOTHER PART OF IT....THAT IS CALLED A CANE

WHAT MEANS...BECAUSE THE FORCE ARM INCREASES...BECAUSE THE PULLEY

DISTANCE CHANGES...AS IF THAT FORCE ARM INCREASE...THE MECHANICS

OF THAT MACHINE...ALLOWS THE WEIGHT TO GET LIGHTER...EVEN THE WEIGHT

OF THE STACK IS STILL 10KG...

*IN FACT WHAT THOSE MACHINE ARE MADE TO DO.....IF YOU HAVE A 50KG STACK..

AT YOUR STICKING POINT....THE CANE GETS BIGGER....AND WHEN YOUR WEAKER

FROM A MECHANICAL POINT OF VIEUW..THE CANE MAKES UP FOR THAT

WEAKNESS....AND MAKES IT LIGHTER...HENCE IT'S CALLED A VARIABLE

RESISTANCE MACHINE....MECHANICS OF THE MACHINE CHANGING THE ACTUAL

LOAD...BECAUSE OF THE NATURE OF THE CANE....VARIABLE RESISTANCE

MACHINE...WHAT SHOULD MATCH OUR MECHANICAL DISADVANTAGE....WHEN

THE MACHINE HAS IT'S ADVANTAGE..HENCE...MAKES IT ALL EASSIER FOR YOU

TO TRAIN ON

*THE PROBLEM WITH THE MACHINE IS NOT REALLY LIFE LIKE.....LIFE IS NOT

VARIABLE RESISTANCE...LIFE IS CONSTANT RESISTANCE..BUT YOU HAVE TO

APPLY VARIABLE TENSION TO IT....TO OVERCOME IT

*LOAD IS CONSTANT...BUT THE TENSION DEVELOPED IS VARIABLE

*VARIABLE MACHINE TENDS TO MAKE.....IS THE TENSION CONSTANT....BUT THE

LOAD VARIABLE....IN LIFE THE LOAD IS NOT VARIABLE....IT IS CONSTANT ON US

*WE HAVE STICKING POINTS IN ALL OF OUR MECHANICAL ATTRIBUTES....AND WE

KNOW NATURALLY WHERE THEY ARE...INSTINCTIVLEY WE KNOW WHERE THEY ARE

WHEN WE ASK TO DO A TASK....WE PUTTING OURSELF IN THE STRONGEST

POSITION...WHAT IS RELATED TO OUR MECHANICAL ADVANTAGE....NOT TO OUR

MUSCLE OPTIMAL LENGTH.....BECAUSE MECHANICS RULES US...IT REALLY IS

THE PREDOMINATE THING WHAT DICTATES OUR PERFORMANCE

*A MUSCLE WILL UTILIZE LENGTH TENSION ..ONLY BECAUSE MECHANICS IS FAILING

AT THAT PARTICULAR POINT IN TIME....SO WE ARE BUILD THAT WAY
