Shaking the hula hoop is a full-body exercise, which can achieve the effect of slimming, but the exercise time must be long enough. Because the intensity of hula-hoop shaking is not very strong, only by extending the exercise time and continuing to exercise to the stage of aerobic exercise can we consume the fat and excess calories stored in the body. How long should I shake it to achieve fitness effect? You may wish to refer to the "333" campaign promoted by the State Sports Commission. You should exercise for at least 30 minutes three times a week, and your heart will beat 130 times. Because the exercise intensity of shaking hula hoop is not enough, if you want to improve your heart rate, you must speed up the shaking. Exercise frequency: 4~6 times a week, 2~3 groups each time, 20~30 minutes for each group, and 20~30 minutes for rest between groups, generally no more than 45 minutes. Note: The waist rotation exercise belongs to moderate exercise intensity. Teenagers, people with poor waist and abdominal muscle strength, obese middle-aged people, young men and women with more waist fat accumulation, and people with a large proportion of waist circumference measured by physique. Children and the elderly should use it with caution. Patients with lumbar hyperosteogeny and lumbar disc herniation are contraindicated, and patients with hypertension and heart disease are not suitable.
