A

Stand with feet hip-width apart and hold one 8-pound dumbbell horizontally in front of your chest, an end in each hand so palms face each other, elbows bent and close to your sides. Contract abs, keep chest lifted, and lunge back with right foot, lowering until left thigh is parallel to ground and knee is aligned over ankle. At the same time, turn your torso slightly, and lower the dumbbell toward your left hip [A].

B

Straighten legs and lift dumbbell up and over your right shoulder, elbows slightly bent [B]. Lower into lunge once more as you contract abs and return the weight to the starting position, and repeat.
