Extremely RIPPED! is part of the Endurance phase. This workout amps up the intensity with non-stop compound exercises. This class guarantees both benefits of strength training and of aerobic cardio training. Although there are no cardio intervals in this class, the high-rep compound exercises combined with active recovery and no rest between tracks mean you will achieve the same cardio benefits and calorie burn as if you were running on a treadmill. This high-intensity class keeps your heart rate elevated throughout the workout, and the high reps build lactic acid in your muscles to stimulate muscle endurance. Research shows that high-intensity resistance training can burn almost twice as many calories as a low intensity workout AND you will continue to burn calories at this accelerated rate for hours after your workout. Modifications are shown for all fitness levels! Get your sweat on with Get Extremely RIPPED!-the results are waiting for you.
