Try the split lunge dumbbell pass which targets your obliques, thighs, butt, and shoulders: Start in a lunge position with left foot forward, holding a single dumbbell in your right hand. As you bend knees to lower into a lunge, pass the dumbbell under left leg then raise left arm until parallel to floor as legs straighten, that’s 1 rep. Do 12 reps then switch sides. Remember, you have to challenge your body to change your body. Watch the video below for a super effective core move, and try these crunch-free core moves to help slim your waist.
