(1) Double exercise core, girls and boys hold each other's ankles, take a deep breath and then push each other's abdomen when exhaling. Girls' hips are raised and boys' backs are straight, which helps to exercise each other's core and strengthen mutual trust. Do three groups every day for 20 seconds, with a rest 10 seconds.

(2) The hands and feet are slender, the boys' feet are slightly wider than the shoulders, the girls hold the back of the sofa with both hands, the boys hold the girls' ankles with both hands, take a deep breath, the boys squat, and the girls' elbows are pressed down for 30 seconds, and they exchange with each other to complete three groups.

(3) The thighs are thin, and the girls' feet are wider than their shoulders. After squatting, their hips are pushed up, and they take a posture of squatting with their hands up at 45 degrees. Boys are opposite girls, doing leg lifts in situ. Every time I lift my leg, I will touch the girl's palm. After 30 seconds, they will exchange with each other and complete three groups.

(4) Push-ups+squats, boys hold the ground with both hands, girls stand well, feet are wider than shoulders, boys' ankles are held with both hands, and they go down together. Girls continue to squat, boys do push-ups, and their chests are as close to the ground as possible. After 30 seconds, the two sides exchange and do three groups every day.

(5) Flat support: two people do flat support together, then cross their hands tightly, lift the opposite legs respectively, and keep the posture motionless 15 seconds, then return to the initial posture, with the body down, and exchange hands and legs when getting up again. Repeat 12 times as a group, one * * *, and do 3 groups. The flat support is simple in action and has a good weight loss effect. One action can stimulate more than 60% muscle groups in the whole body. When couples do this action together, it can not only increase the fun of sports.
