Because the hula hoop shaking mainly depends on the waist, it fully exercises the waist muscles, abdominal muscles, lateral lumbar muscles and other parts. Insisting on exercise can achieve the effect of tightening the waist and abdomen. 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 exercise for at least 30 minutes three times a week, and your heart beats 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.
