Muscle soreness

Sore muscles are not a sign of a successful workout but of a workout that went beyond what's healthy; delayed-onset muscle soreness (DOMS) has been shown to be caused by micro injuries primarily to tendons and ligaments.

Up until the 80s, we would be told anywhere: no pain, no gain! If your wouldn't feel your muscles the next day, you wouldn't develop additional muscles. A workout in the gym would have to cause what is medically termed as delayed-onset muscle soreness (DOMS), otherwise you wouldn't develop your biceps or latissimus.

In many gyms, we still hear the same myth... and a myth it is. For it has been proven by biopsies (removal and examination of a sample of tissue from a living body for diagnostic purposes) that the soreness that follows a day after vigorous exercise has nothing to do with muscle growth or deposits of lactic acid but simply is the result of micro injuries to ligaments (tough, fibrous tissue connecting bones or cartilages at joints) and tendons (tough, inelastic fibrous tissue that connects muscles with their bony attachment).
