I'm out of shape

I enjoy working out, but I am a horrible procrastinator. "I'll start back working out tomorrow," I tell myself. Always tomorrow. *sigh*
However, I am a certified professional swimming instructor and have taught all sorts of classes, all ages from newborn parent/tot classes to 60yr old women! My heart really lies in swimming instruction and I wish I lived in a city that brought in better business. I used to work full time for myself as a swimming instructor in Charleston, but since moving to Tennessee, water safety isn't as important to residents here, nor is the average household income as high...which is ok, but I do miss being fought over!
Until May, I worked out at the college gym on my spouse membership...but my husband graduated in May, and there went my state-of-the-art gym membership, grrr! They also had an olympic sized pool I used to do laps in twice a week!!!!


So these days I'm sadly out of shape. BUT, I'm looking for a good workout video - any suggestions? I want something fairly short to fit in my schedule but something that would have a good cardio workout. (I can do stretches and weights, etc. on my own.)
