that is excellent.
what are you at, height, weight, and your lifts.
here is something to try. do a set of something, walk directly over to a cardio machine and work hard on it for 45-50 seconds burning 13-15 calories, walk to a clear area and do 25-30 push ups, then do 50 crunches. get some water and repeat that 10 times or so without much break. its a different kind of program, something you could mix in once a week or do for a month if you wanted. it gets a good sweat, works a lot of muscle groups, and gets a lot out of your time. the quick 'burst' work is good for cutting and not losing as much muscle with your cardio.
