Begin by holding dumbbells in your hands, core tight and back straight. With a slight bend in the knees and while keeping a flat back, slowly bend forward at the waist, allowing the dumbbells to low down. When you reach the bottom, slowly rise back up using your hamstrings and glutes. As you come to the top of the movement, squeeze in through your glutes. Be sure to maintain a straight back position with a line from your shoulders through your hips.
Julie's Tip: This intermediate can be made more difficult by utilizing a balancing BOSU which engages the entire body.
