Hi all! I''m looking for a high-impact/intensity workout video for my home. I normally like to run outside, but its too cold out! I feel that most of the home workout videos don''t give me as much of a workout as I would like. I normally run about 4 miles 3-4 times per week. I have heard good things about P90X videos (Linky). They are really expensive though. I do have a set of free weights at home, so any videos that use those would be good as well. Any ideas?
