The Olmecs, like many cultures, apparently considered grounding or centering yourself to be the beginning of the spiritual/physical journey and an internal prerequisite to doing good in the external world. An enlightened soul can enlighten others, but the blind leading the blind will cause both to stumble. The Olmecs had a symbol to represent this connection with earth: the were-jaguar. This human/animal hybrid possessed the sturdy, supple life-force of the muscular jungle cat.
Likewise, exercises must be performed with both solid grounding and relaxed flexibility. Perfect form and maximum intensity are far more important than using much weight or many repetitions. There should be a focused obsession with form and intensity, only increasing weight and repetitions when these more crucial factors can still be maintained. Changing form can involve unintended muscles producing inferior results or even injury. Proper form isolates the correct muscle. Proper force, resistance, and repetition maximize the correct muscle.
