i don't take a rest. i am in the 20-something thread a lot and there are many of us doing the 30ds there. i don't believe very many of us take a rest. i don't feel like it is necessary. i don't think the strength training that we do is so intensive it requires a rest. just my opinion though. you know what your body needs. if you feel like resting, then do so, but if you feel like you don't need to, don't.
First goal: lowest weight I remember being in the last 10 years
