Timothy Abraham has just tweeted that a bit more info on the reasons behind it will be hitting the web tonight.
He also said there's something on VT which gives the gist of what it is about, and it the post i think he is referring to is about some of the senior pros not liking how hard Robert Duverne is working them at this stage of the season, Collins and Dunne among them.
Also that MON used to train them much less hard and give them more time off, and they're not happy with the arrangements now.
Also goes on to say that the younger players at the club absolutely love the new training regime.
I find it hard to find much sympathy for extremely well paid athletes complaining about having to do actual work rather than mope around golf courses all afternoon (or pubs in the case of Dunne). I know that's a simplification of the matter, but it's my gut instinct, nonetheless.
