Way back when, certainly in series 3 and 4 when much of the storyline was about Boy’s rivalries
North/South Yorkshire for Darren Gough and James Martin and Cricket v Rugby for Mark and Matt the training hours were shown and were getting up to ridiculous levels even then. At some point that was stopped and people grizzled that you ‘couldn’t see how much they were putting into it’ (probably around the time it backfired on them showing John Sargent reading a paper rather than training) which is daft any way … because the technically earliest 10 in Strictly history for Louisa’s second dance of a jive was given after about 9 hours of training due to a Vincent crocking his back and Michael Vaughan trained relentlessly for a jive that while awesome was always also going to be complete pants.
Just because you train 50 hours a week, doesn't mean it’s going to be any good.
