The 'trainers tip' on the Biggest Loser USA, i.e. the programme which employs the very same Jillian Michels of 30 days Shred fame, advocates not working the same muscles groups for two consecutive days? - and the importance of the occasional rest day for muscle repair.
Is it just me, or is this entirely at odds with Jillians 30 day shred, namely following the same basic 20 minute routine day after day without variation?
