I’m curious as to why metabolic conditioning was removed from the Nautilus principles. After all, Jones had trained Casey & Sergio at a fast pace with good results and you had the results of the West Point Study to tell you the protocol worked well. Why then move away from what appeared to be the ultimate form of exercise (in terms of results & efficiency) to focus almost exclusively on failure?
If I’m a gambling man, I’d guess Jones was looking to appeal to bodybuilders & figured they’d reject a fast paced, circuit training style workout offhand, but they’d more readily accept training to failure. But that’s just my guess.
Really interested in your thoughts.
