Start with your feet shoulder width apart. Hold the dumbbells at your side, palms out.

Take a step back, diagonally, shifting your weight on the reverse leg. Be sure to keep the forward knee in line with the middle of your foot.

As you go into a lunge position, perform a bicep curl, lifting your dumbbells toward your shoulders. Keep your elbows in line with your shoulders at a 90 degree angle.

Push off the front foot and lower the dumbbells away from the shoulder.

Return to starting position and alternate legs.
