4. Slim & Strong

The Slim & Strong workout starts with a metabolic sequence sure to define every single muscle in you body and create an intense fat burning effect. The workout then progresses to burning out every single muscle, so that you can be sure to take that rest day guilt-free. Only 2 workouts a week will create an attractive, athletic, and lean shape. Define your arms and shoulders, firm and strengthen your thighs, and lift your butt, while boosting your cardiovascular endurance. Enjoy the intense after burn effect—the amount of fat you burn long after you walk out of the class.
