If you are a girl, you can try flat support or do shoulder-elbow handstand. After handstand, your legs can be extended to both sides, or you can do ground movement. For thin arms, you can choose 2.5KG dumbbells to do corresponding training. Attention, don't pull it up. Because you don't go to the gym and have no professional equipment and coach's guidance, you should pay attention to strength and relaxation when training at home!
