Run 1 hour every morning, do push-ups+sit-ups+squats every day, and measure yourself every time until you reach the limit. If you have spare money, buy a pair of 30kg dumbbells for exercise.

It is estimated that you will not insist, even if you insist, your figure will be out of shape. You take fitness too simply. Without the guidance of a professional coach, you will play by yourself sooner or later.
