 Diff leg deadlift. Take a firm overhand grip on two dumbbells, then raise the dumbbells until it is hanging in front of the thighs. Keeping the arms and legs straight, bend forward until the barbell almost touches the floor. Return to the erect position without pausing, bringing the shoulders well back. Inhale as the weight is raised, exhale as it is lowered. Reps 8 to 12. Note, use light weights to avoid back injury. Can also be done with barbell.
