I recommend you to keep fit and improve your physical fitness. Aerobic exercise: running, high jump, swimming, anaerobic exercise: if there is no condition, do abdominal support at home and practice pectoralis major and triceps brachii, trapezius and deltoid; Sit-ups can practice abdominal muscles; Squat, you can practice thigh muscles; Lifting the heel (lifting his body up with his toes) can practice calf muscles; Playing dumbbells properly can train upper body muscles. Aerobic exercise should be combined with anaerobic exercise. Anaerobic exercise should not be practiced every day, but every other day. Scientific fitness will naturally have a strong body. Usually eat more high-protein foods, such as eggs, milk, meat, fish and so on.
