During the COVID-19 was Quarantined at home, you may worried about the lack of exercise and get fat, remember to do these exercises can be helpful. 
Due to the impact of the COVID-19 , many people were forced to stay at home. During this period of time, I believe everyone was very bored, and every day after eating, they would watch TV, play mobile phones and play games to relax.  However, the long-term reduction of exercise at home will also bring some health problems to our body, such as obesity, physical decline, etc., so affected by the venue and equipment, what is the best exercise to do at home?  
We spend most of our time just sitting and lying down, which can lead to the accumulation of belly fat, so let me recommends these exercises to reduce belly fat!

First position：Two hands straight arm support, back  keep straight, tighten the abdomen, left leg kneel 90 degrees, instep close to the ground, right leg straight tiptoe, and swing up and down your leg.  Repeat 20 times, switch sides and continue.  

Second position: Start in a plank position with your back straight and remember to tighten your stomach, with one leg supporting the floor and the other leg lifting and swinging up and down.  Do this 25 times, then switch sides .

Third position: Very similar with the last movement, do the plank position first, tighten the abdomen,using elbows and both hands support the ground, the toes also support the ground, Use your hip strength to turn around the body side by side.

Fourth position: the upper body is clingy to the ground, both hands are placed on both sides of the body, the legs are carried upwards, and with the ground i90 degrees, the legs are up and down , and two leg are like a scissor, this action is repeated 25 times.  

For the last position, sit on the mat with your hands crossed across your chest, legs together at a 45 degree Angle, thighs stay still, using calves up and down. Repeat 25 times.
