Kettlebell exercises combine cardio and strength training to tighten up your trouble zones in no time. No kettlebell? You can use a dumbbell instead.
How to do it: Hold a kettlebell (or dumbbell) with both hands and stand with your feet hip-width apart, knees slightly bent. Bend at your hips and lower your torso until it forms a 45-degree angle to the floor, keeping lower back naturally arched. Swing the kettlebell between your legs. Keeping your arms straight, thrust your hips forward, straighten your knees, and swing the kettlebell up to belly-button/chest level. Continue swinging until you've completed 10 reps with a challenging weight (17 to 26lb kettlebell depending on your fitness level).
