A week is unlikely to have much effect unless you go to a special slimming center.

Don't exercise this week, do more leg exercises, such as lying flat on the bed, raising one foot as high as possible, then putting down the other foot and doing it alternately with both legs, about 15 times, and insist on it every day.

Another way is to face the wall, with your feet shoulder-width apart, hold the wall with both hands, and bend one foot backwards until you can't bend it any more. It may be helpful to keep this position for about 5 minutes and change your feet alternately.
