One hundred sit-ups every day. Or, if possible, do yoga for an hour every day and recommend several simple postures ~ leg beauty skills: First, crow style. 1) Kneel on the floor, put your knees together, separate your feet, put your hips on the floor between your feet and breathe naturally. 2) Lift your hips up, put your toes on the ground and sit on your heels. 3) Lift your knees up, put your heels on the ground, and put your palms on the outside of your feet. Breathe naturally and stay in this position for as long as possible. (Note: At this time, the palms should be close to the ground, and the upper body and chest should lean back as far as possible). 4) Slowly return to the preparation posture and have a full rest. Second, the tree type. 1) Stand up straight, hang your arms to your sides, and breathe naturally. 2) Stand with your left leg, bend your right leg from your knee, lift your right leg to your left thigh, and rest your heel and sole on the upper part of your left thigh. (Note: The lateral heel should be pressed tightly on the left thigh, and the left leg and the whole body should be tight and straight at this time). 3) Raise your hands from your sides to your head. When you hold them above your head, put your hands together on your head and put your wrists against your head. 4) Stretch the bent elbow backwards as far as possible, so that both elbows are in the same straight line. Look ahead, with your left leg taut, your whole body in a state of tension, breathe naturally, imagine yourself as a tree with indomitable spirit, and keep this posture 10 second. Note: You can stand comfortably by bearing the center of gravity with the heel of your standing foot. 5) Let go of the palm of your hand, put your arms back to your sides, then grab the toe of your right foot, gently lift your foot back to the ground, return to the preparatory posture, and relax yourself. 6) After a few seconds' rest, practice this posture with your legs alternately for 4~6 times. Skills of reducing abdomen and waist: 1. Tree (same as above) 2. Bend forward. 1) Sit flat on the ground, straighten your legs forward, put your heels and toes together, and hang your hands at your sides. 2) Inhale, with your arms straight forward and parallel to your legs. Lean forward and grab your ankles with both hands. 3) Lower your head between your shoulders, exhale at the same time, tighten your legs, grab your toes with both hands, and put your head between your arms. Hold your breath and hold this position for 5~ 10 seconds. 4) Put your hands on your thighs and inhale. At the same time, the palm slowly retracts along the leg and returns to the posture of 1). Take a break and repeat this action 3~4 times. Third, the cat stretches. 1) Kneel on the ground, put your hands on your thighs and breathe naturally. 2) Hips are raised, palms are placed on the ground in front of knees, and knees and calves are placed on the ground to form a crawling posture of animals. 3) Inhale, raise your head, arch your hips, hold your arms on the ground, contract your back muscles, and hold this position for 5 seconds. 4) Exhale, lower abdomen, bow your head, arch your back in a circle, and hold this position for 5 seconds. 5) Keep your arms straight and perpendicular to the ground, return to the previous crawling posture, and repeat the exercise for 4~8 times. These postures are simple and effective, and the last three postures are my favorite. In addition to slender waist, tree posture can also promote blood circulation of joints, forward flexion can promote digestion, and cat stretching can also help relieve dysmenorrhea and improve irregular menstruation ~
