Lie flat, straighten your legs, and lift at 90 degrees to the bed surface. Spread your legs slowly in the air like scissors, stop for 5 seconds, then close your legs and do it 10 to 15 times in a row. Do one or two rounds a day.
Using the above set of weight-loss exercises, I believe that as long as you persist for one week, you will feel the reduction of leg fat, and if you persist for one month, you will definitely achieve very significant results.
