Stand with your feet hip-width apart. Hold a dumbbell in each hand at your sides.
Step forward with one foot, and slowly lower your hips until your front knee is bent at a 90-degree angle and your back knee is just above the ground. At the same time, curl both dumbbells up to your shoulders without twisting your wrists; hold for one count.
Bring the dumbbells back down to your sides as you press through your heel and return to start position.
