Sure ~! ! But be careful not to be too violent, and take your time when you are tired! ! Otherwise, there will be muscles on your legs. If the muscles are not well trained, the leg shape will not look good. Skating at a constant speed for one or two hours every day and practicing for two weeks will have great effect! ! When I took a roller skating class, the coach said that it was really slimming, not just the legs! ! I lost weight, too! ! Remember not to skate too crazy! !
