I started doing NHE this week, I will be basically doing atkins(carbs 20-30g) with a carbup (low fat) meal on Saturday night, followed by hard weight training(followed by 30min cardio) on Monday and depletion workouts on Wed and Fri 9with Cardio as well. Does this seem like it would work?

I have been going to the gym for four weeks now, and I am feeling great. I have not really lost any weight since then though, which is a little surprising. I need to get a bodyfat meter
is it worth getting those electronic scales or calipers?

My instructor has me on machines to build some basic strength, but I plan to get on the free weights as soon as possible.

One more question, I do a total body weights program on Mon/Wed/Fri, is there much advantage to splitting up targetted body parts, eg: Arms one day, chest the next?
