Stand with your legs hip-distance apart, holding dumbbells at your sides.
Perform a bicep curl, bringing the weights to your shoulders.
Bending your knees and keeping your chest lifted, sit back into a squat like you're sitting into an imaginary chair. Press your weight back into your heels, and keep the dumbbells at your shoulders.
As you push through your heels to stand back up, press the dumbbells straight overhead.
With control, bring the weights back down to your shoulders, then to your sides, returning to your starting position.
