Sweating out water is one of the quickest ways to drop water weight. If you have access to a sauna or a steam room, take a 30 minute soak to sweat out the fluids and toxins in your body.  Spend only 30 minutes at a time in the sauna to avoid dehydration. You will likely gain the water weight back after drinking or eating, but this is a good way to temporary shed water weight for the night. Drinking alcohol can lead to dehydration, which will will then force your body to store excess water to stay hydrated. Avoid that glass of wine or pint of beer before and after exercise to stay hydrated and skip alcoholic beverages for the night if you want to avoid carrying any water weight. Get your heart pounding to pump fresh blood and oxygen to all your tissues, increasing circulation of body fluid and helping the excretory system get rid of waste. Increase the frequency and intensity of your workout for the week to encourage your body to release water weight through sweat. Exercise also elevates your cortisol levels to a healthy level, which helps you work through stress and tension.  High intensity interval training (HIIT) can help you burn fat and sweat out water weight. This type of training is structured around simple, intense exercises, followed by short bursts for recovery or rest.You can perform HIIT exercises with gym equipment, or an exercise mat and a few free weights. There are several popular HIIT programs listed here.
