I bought dumbbells in the dormitory and wanted to practice chest muscles, but it seems that everyone has to lie down to practice, so it is inconvenient to lie in bed. Are there any convenient substitutes, such as cushions? You'd better buy a dumbbell stool, which is more professional. Or a bench

Or in the corner of the bed. Just show your elbow.

Bench press: mainly practice the thickness of pectoralis major and thoracic groove.

Action: put the dumbbell on the bench with both hands, put the dumbbell on the shoulder, and palm up. Push the dumbbell up until the arm is straight, stop for a while, and then slowly recover. Tip: Push-ups and squats are curved, so that pectoralis major can be fully contracted and fully extended.

Lying bird: mainly practicing the middle chest groove.

Action: On the supine stool, hold dumbbells with both hands, palms facing each other, and naturally stretch your arms over your chest. The elbow of the arm is slightly bent to lower the dumbbell to the lowest point on both sides, the pectoral muscle is fully extended, and the pectoral muscle is forcibly contracted to lift and restore the arm.
