I am a boy, 18 years old, weighing 80kg. I want to lose weight. What exercise can experts do in bed before going to bed?
The simplest way is: you must eat breakfast. Eat seven minutes full at lunch. Eat less for dinner.
Insist on playing ball every night. You can do 30 sit-ups in bed. Sit-ups are important in persistence.
Then there is another important point. Never eat dinner.
