The first kind, bed exercise, the bed is actually cleaner than the floor, many people like to do push-ups, sit-ups, grab hands and other sports in bed.

Sit-ups: A group of 30 is recommended. You can stick your feet on the railing at the end of the bed or find a roommate, leg press. Later, you can do it yourself after the abdominal strength increases.

Grip strength: after doing sit-ups, start to practice clenching fist, then loosen it and clench fist again.

The second type: high and low bed belly rolling, an action similar to horizontal bar belly rolling in sports. This action requires enough arm strength and abdominal strength to complete. Generally speaking, the thinner people do the horizontal bar, the easier it is to break the record. Remember the arm strength first, and then remember the sequential skills of abdominal strength.

The third kind, shoulder and back, can also be called double squat. If there is no strength foundation, it is recommended to do squats before standing up, and then challenge roommates to do squats later.

Push-ups: It is recommended to rest for 30 seconds for other sports, with the chest slightly close to the bed, the included angle between arms less than 90 degrees, and the buttocks must be pressed down. Lift up with your body when you get up. If the later exercise is successful, switch to one-handed push-ups.
