When bending down to pick up things, bend your waist or thighs like touching your toes, which can strengthen the muscles of thighs and buttocks (people with back problems should avoid this action). When walking, stand up straight and look up like a puppet walking in a straight line. Take advantage of the free time of cooking or washing dishes, take the kitchen as a ballet practice place, stand at the kitchen table 90cm away, hold the edge of the table with your left hand, lift your right leg, straighten your knees and toes, swing back and forth 10 times, repeat with your left leg, then straighten your arms and face the sink, hold the edge of the pool and bend your knees for 5 seconds. I often buy some heavy clothes to wear at home. This is not to make you "grow up" to wear fat clothes, but to make you "feel guilty because of obesity" after wearing this kind of clothes. It doesn't cost much, but you can lose weight quickly. This is just a psychological "first aid".
