It is not suitable for exercise before and after meals 1 hour. You can exercise without fitness equipment at home, even your leg strength can be practiced. Don't squat for too long at first, and do several groups slowly. When practicing abdominal muscles, you can do double-headed warping (lying flat, then lifting your hands and feet at the same time and touching your feet once), and you can do several groups appropriately. Just do push-ups with your arms. Squat posture can also practice arm strength. After squatting, raise your arm in advance to touch the ground in parallel to catch the air (clench your fist after your fingers are opened) and repeat the exercise.
