I feel that resistance training should be the main form of excersize that you do. Since you are restricting calories you will lose fat. Maybe cardio can accelerate the process, but retaining your muscle and improving your general health should be the goals of excersize... These things can be achieved by resistance training.
I generaly work one bodypart per day... about 8 sets. Taking one or two days off per week. (these workouts rarely take more than 30 mins.)
Cardio sessions are always seperate from resistance, about 4 times per week for 20 min. HIIT
