1. Stand naturally, raise dumbbells with both hands, straighten your arms naturally, keep your feet shoulder-width, bend your knees slightly, keep your back straight and slightly arched;
2? Fold your hips backward, bend your knees and bend over, and the dumbbell falls along the front side of your calf, staying for 2-3 seconds until the lowest point of action, and feel the muscles of your hips stretched;
3? Straighten your back, tighten your hips and lift the bell. Say it again.
