We love the Tabata protocol for quick, efficient workouts. The simple structure, 20-second intense intervals followed by 10 seconds rest for four minutes, means you can really push yourself. Not only do you build strength, but you burn more calories during and after your workout. Try two rounds of Tabata with Equinox trainer Dana McCaw. Press play for the warmup and workout. And, of course, to sweat.
