Stand with your feet slightly wider than hip-width apart. Hold a weight (dumbbell, kettlebell, or weight substitute) in both hands at the centre of your body with your arms fully extended, shoulders back, and arms relaxed.
Bend at the hips and pull your core in toward your spine, keeping your spine straight and chest lifted. Continue to bend until the weight is near your shins or as far as you can go without losing proper form. Let the weight hang down without hunching your shoulders. Your knees should be slightly bent and your chest parallel with the floor, not rounding your lower back at any time.
Drive through your feet to stand, keeping your arms relaxed down as you return to the starting position. Push your hips forward once you're standing to engage your glutes. This counts as one rep.
