Standing tall with the dumbbells at your sides, step out to one side while also pushing your hips behind you and sit into that hip.
As your hips drive back, your upper body will naturally come forward a bit, but keep your back long to not let your chest round down. The weights will frame the now-bent leg.
Once at your appropriate depth, drive through the floor and push back to the starting point.
Complete 8-12 reps per leg.
Tip: You can stick to the same side or, for a challenge, you can alternate sides.
