Question:

I'm getting back into lifting and I'm doing biceps, triceps, shoulders and chest on the same day and back & legs on the other.  I 'm really making progress but not as much as I would like.

Answer:

That is good you are losing weight keep it up and make sure you are toning those muscle at the same time.  There is nothing wrong with doing several body parts in one day but you need to make sure you are hitting everything correctly.  I would start breaking it down even more into less body part a day.  Make sure you do cardio almost everyday.  Two days a week need to be all cardio days and you can do something like below for the other three.  I would do 5 minutes cardio before and 15 minutes cardio after this workout on your weight days.
