To be fair mate most top level fighters use these coaches.. May weather , Pacqueo, Rios, Alvarez, klitscho and our own Khan.. They do improve boxers and there are some good and some bad same with everything
I never said that the changes were "dramatic" but fights are often decided on the tiniest of fractions. Every advantage you can gain gives you a better chance than you had before of winning. If we compared the fitness capacity of a modern day fighter who embraces the latest scientific methods to the fitness capacities of a fighter in the 1970s then I believe the differences would be dramatic. These could be measured using loads of different tests- not a subjective look at how they fight over distance.
It's down to what works for individuals. Different things motivate people to put in the work needed. And different things do the trick for different folks. There's more than one way to skin a rabbit. Thinking in straight lines is the problem, not whether or not you need s & c specialists.
Ulimately you need to be able to fight for 12 rounds at a good pace, in the older days they fought for longer rounds, alot of fighters these days gas out in some cases quite early in a fight. Why is this with all the modern techniques and technology and more nutritional knowledge? So then it must be down to a poorer discipline and attitude? Imo if you are being put through the right training you shouldnt be gassing out or at least not until right at the end.
That is a fair point, In todays pro game the word professional seems to have lost most of its weight, and I'm not talking about top pro's, because most of which are paid enough to fund their profession and in other cases live a wealthy-ish life style. Its more common in the lower end pro's, that said, we are commonly seeing British champions struggling to look good over 10 or 12 rounds, at that level (in theory) you should be ready or nearly ready for a world title shot. No pro boxer who is dedicated to his craft should be completely gassing in a hard fought 12 round fight, unless the fight turns into a battle of attrition, in which its normally the case that both fighters, despite how fit they are will hit a wall.
Some people still swear by them. I did loads of these when I was in my twenties and my shoulders are now giving me trouble in my forties; not sure if it's the exercise or age, though!
