PX90 Question...

kysue1029

I have been running for a little over a year now. I run anywhere from 10-20 miles a week. Since it's getting so hot outside, I am looking for something to do around the house. I (well my husband) has the PX90 DVDs and I was wondering if it would be a good workout to do just every now and then when I can't get out and run? Also, if I am wanting a good cardio DVD, would the cardio one be too intense for me if I'm not doing the whole program? TIA!
