Not sure if the UK has this or will have it soon - but I watched the first episode of this last night
car crash TV
It is just the best/worst TV EVER!
I don't think I can bare to watch it again, but the training and competition are fierce, mums saying 'she can shout at my daughter, she can slap my daughter, so long as she gets results'. The gym trainer (who is fierce but fair) is the nicest person on there.
The mums are incredible - calling each other into side rooms to shout and call them a bitch, saying how high their status is, and whether they'll let other mums be in their crowd etc. It makes school gate politics look fluffy.
