2 Walking Lunge
Sets: 3 Reps: 10-12 (each leg)
Hold a dumbbell in each hand and step forward with one leg and lower your body until your front thigh is parallel to the floor. Your shin and thigh should form a 90-degree angle. Your back leg should be bent so that your knee hovers slightly above the floor. Push off from your front leg and step forward with your other leg. If you don't have space to walk across your gym, perform lunges in place by alternating legs.
