Query: Great workout!

I was used to walking 2 miles a day, but even the one mile workout on this DVD gives me a good sweat, and uses lots of muscles I forgot I had. I am not a huge fan of exercise videos, but got this to replace water aerobics over the winter. I get bored with it, but that is me. If you like exercise videos, and need a good quick workout that will get you moving and your heart pumping, the one mile WATP is excellent.
