Wii or DVD recommendations, please

Hello-

I started exercising again on Jan. 2. It had been over 2.5 years since I went to the gym and it took me about a month to get my body back into the routine. Before I stopped exercises I was running about 25 miles/week. I did JM 30DS from the middle of Jan to the mid of Feb. It worked great for me b/c it was short, so I could not make any excuses to not do it, and I felt like I got a work-out. When I finished the 30DS, I had built up my endurance enough to run 3 miles comfortably. So, I decided to train for a half-marathon later this year. I would like to add some sort of cross-training/strength training/toning/abs-core workout to my routine for me to do 2 days/week. That is short and that I can do from home with free weights. Any recommendations?
