Disco Sweat is pure Richard Simmons: "get-up-and-dance" oldies and a bevy of exercisers of all shapes, sizes, and clothing styles, shaking their booties with abandon and joy. This time they're boogying at the "Brooklyn Disco" under flashing lights. The music is all 1970s disco, with songs like "Mighty Real," "Boogie Fever," "Born to Be Alive," "Last Dance," "I Love the Nightlife," and "I Will Survive," accompanied by special effects such as a silver ball overhead or bubbles from a "car wash." Richard's choreography, as always, is easy and accessible to beginners: light, low-impact moves, repeated often. A few songs are especially fast for higher-intensity intervals, but the moves are still low-impact and uncomplicated. An occasional "disco point" of the fingers or "Travolta arms" add effect. After you dance your buns off, Richard takes you to the floor for ab work and stretching. This is a long workout, and if you're just starting, you may not have the stamina to do the whole tape. Just do what you can on this 70-minute video, taking frequent breaks, and each week you'll be able to do more. --Joan Price
