Abdominal/Upper Body Workout???

what would suggest doing for an Upper Body and Abdominal workout? I’ve been walking about 2-3 miles a day, which I can feel in my legs, but I think I have been neglecting my upper body. What do you suggest. I’ve been thinking about getting Hip Hop Abs. I’d really like to hit my midsection seeing as I need to do some chest work as well as Abdominal. Thanks.
