The second episode ~ the one where you lift the dumbbell to jump can thin your arm ~ ~ One of the actions is to lift the dumbbell ~ above your head ~ and then put it behind your back ~ and pull it back to your head to thin your arm! (During this period, the boom can't swing back and forth ~ Always keep it at both sides of the ear, and test the strength of lifting dumbbells and putting them down on the back of the boom. ) This movement is also taught by my fitness instructor ~ ~ I specialize in slimming the back of my arms ~ ~, and the calf is the most difficult place to lose weight, because most of it is muscle, you can just follow aerobics ~ ~ After jumping, spend more time on stretching and massaging the calf ~ You will naturally lose weight ~
