Light Training vs. Heavy Training
On a short conditioning period and Iam talking about Conditioning not the so-called "pre-con", a 14-day keep is ideal for healthy birds. This has been proven 20-30 years ago as to the matter of so-called 21-day keep, it is really a matter of how you point your birds to peak on fight day, regardless if its 14-days, 21 or even 30 days. These are, as a matter of personal opinion, just trying to overly emphasize a period of time but, the bottom line is and will always be the ability of the Trainer/Conditioner to pick the right bird to be conditioned in simple terminology.
To be overly scientific, loosing the "feel" but instead going to the motion of conditioning without the Heart is useless. And simply following very basic guidelines without using your own discerning mind will yield nothing except, robotized copying of conditioning. And when we copy, total achievement is completely lost and victory(ies) in the pit is rendered nugatory or doubtful even in the mind of the cock owner or the trainer, because we merely copied.
As a matter of personal opinion, I prefer hard training than light training. This is my belief and I hope the same is respected. Ofcourse, with the corresponding resting period pro-rated with the heavy training, they must jive.
