Putting your hands crossed behind a straight horse is a sitting posture, but stretching your legs can also promote blood circulation, exercise your legs, eliminate leg fat, make your legs lose weight unconsciously, and beautify leg lines. You can sit directly in the middle of the yoga mat, spread your legs to both sides and keep them straight, and press your whole leg on the ground to keep your upper body upright. Keep your hands folded on your back, and the outside of your palm is attached to your spine.
