I too am on the Fat Smashing Diet. This is day 10 for me. I haven't lifted weights during the first phase, b/c just from my own perception of the diet I don't think your body is getting an adequate amount of protein in order to heal or/recooperate from the lifting. And I would hate to pull a muscle or continue to be sore, just because I need a little more protein. What I have done is the Tae-bo Bootcamp, which does have some light resistance training (but that is using bands). I hope this helps.
