Being rational about any fitness routine you desire to begin should require one to completely understand why working out for a limited amount of time is imperative. A simple approach would be personal research starting with talking to professionals including personal trainers, nutritionists, sports doctors, reading credible articles and books, or simply speaking to someone who has been working out for years and has experimented a vast amount of health and fitness routines. The issue I’m addressing is what I call ‘ignorance of research’. This is extremely important to those who haven’t the slightest clue about what too much cardio can do to the human body.
Chronic Cardio, as Mark Sisson, Author of The Primal Blueprint, calls it, is a former triathlete who for years put wear and tear on his body, to, in his mental set, “become better.” He was used to running & training for hours on end daily, but when it was over, he was tired & had created within himself a “catabolic burn out.” There was no energy left to give for anything else and as he says “When I looked like a picture of health, I was really one of overstress and inflammation. I was the fittest guy my friends knew, yet I suffered from recurring bouts of fatigue, osteoarthritis in both my feet, severe tendinitis in my hip joints, stress-related gastrointestinal maladies, and six or more upper respiratory tract infections each year.”
