Fast walking, jogging and swimming are the best aerobic exercises to lose weight. Hula hoop is only for waist and abdomen to lose weight, and the weight loss effect is quite slow.
If you exercise after dinner, I suggest you go quickly. Jogging is better. It is reasonable for you to exercise for 60 minutes.
In addition to exercise, please pay attention to your diet, don't overeat, don't eat greasy, fried, salty, sweet and high-fat food, don't drink, eat less staple food, eat less meat and eat more fruits and vegetables. You will lose weight better through exercise.
I wish you success in slimming!
